3 | # NEWS for rsync 3.2.2 (UNRELEASED) | |
4 | ||
5 | Protocol: 31 (unchanged) | |
6 | ||
7 | ## Changes since 3.2.1: | |
8 | ||
9 | ### BUG FIXES: | |
10 | ||
317beebe WD |
11 | - Avoid a crash when a daemon module enables `transfer logging` without |
12 | setting a `log format` value. | |
13 | ||
fe2ef556 | 14 | - Fixed installing rsync-ssl script from an alternate build dir. |
d15cfef9 | 15 | |
76064b1b WD |
16 | - Fixed the updating of configure.sh from an alternate build dir. |
17 | ||
d15cfef9 WD |
18 | - Apple requires the asm function name to begin with an underscore. |
19 | ||
20 | - Avoid a test failure in the daemon test when --atimes is disabled. | |
21 | ||
22 | ### ENHANCEMENTS: | |
23 | ||
61971acb WD |
24 | - Allow the server side to restrict checksum & compression choices via the |
25 | same environment variables the client uses. The env vars can be divided | |
26 | into "client list & server list" by the "`&`" char or the same list can | |
27 | apply to both. | |
d15cfef9 | 28 | |
f805d1a7 | 29 | - Simplify how the negotiation environment variables apply when interacting |
8df76691 | 30 | with an older rsync version and when they contain only invalid names. |
d15cfef9 | 31 | |
89827e49 WD |
32 | - Do not allow a negotiated checksum or compression choice of "none" unless |
33 | the user authorized it via an environment variable or command-line option. | |
34 | ||
11eb67ee WD |
35 | - Added the `--max-alloc=SIZE` option to be able to override the memory |
36 | allocator's sanity-check limit. It defaults to 1G (as before) but the error | |
37 | message when exceeding it specifically mentions the new option so that you | |
38 | can differentiate an out-of-memory error from a failure of this limit. It | |
39 | also allows you to specify the value via the RSYNC_MAX_ALLOC environment | |
40 | variable. | |
41 | ||
42 | - The memory allocation functions now automatically check for a failure and | |
43 | die when out of memory. This eliminated some caller-side check-and-die | |
44 | code and added some missing sanity-checking of allocations. | |
d15cfef9 | 45 | |
11eb67ee WD |
46 | - Improved the man page a bit more. |
47 | ||
f805d1a7 WD |
48 | ### PACKAGING RELATED: |
49 | ||
50 | - Prepared the checksum code for an upcoming xxHash release that provides new | |
8df76691 WD |
51 | XXH3 (64-bit) & XXH128 (128-bit) checksum routines. These will not be |
52 | compiled into rsync until the xxhash v0.8.0 include files are installed on | |
53 | the build host, and that release is a few weeks away at the time this was | |
54 | written. So, if it's now the future and you have packaged and installed | |
55 | xxhash-0.8.0-devel, a fresh rebuild of rsync 3.2.2 will give you the new | |
56 | checksum routines. Just make sure that the new rsync package depends on | |
57 | xxhash >= 0.8.0. | |
f805d1a7 | 58 | |
7039d146 WD |
59 | ### DEVELOPER RELATED: |
60 | ||
61 | - Moved the version number out of configure.ac into its own version.h file so | |
62 | that we don't need to reconfigure just because the version number changes. | |
63 | ||

bcb0a24a WD |
68 | |
69 | Protocol: 31 (unchanged) | |
70 | ||
68c45836 | 71 | ## Changes since 3.2.0: |
bcb0a24a WD |
72 | |
73 | ### BUG FIXES: | |
74 | ||
246d117d WD |
75 | - Fixed a potential build issue with the MD5 assembly-language code by |
76 | removing some non-portable directives. | |
f8c6f9f4 WD |
77 | |
78 | - Use the preprocessor with the asm file to ensure that if the code is | |
68c45836 | 79 | unneeded, it doesn't get built. |
bcb0a24a | 80 | |
f4e6fe54 | 81 | - Avoid the stack getting set to executable when including the asm code. |
bcb0a24a | 82 | |
3f776f58 WD |
83 | - Some improvements in the SIMD configure testing to try to avoid build |
84 | issues, such as avoiding a clang++ core dump when `-g` is combined with | |
85 | `-O2`. Note that clang++ is quite buggy in this area, and it does still | |
86 | crash for some folks, so just use `--disable-simd` if you need to avoid | |
246d117d | 87 | their buggy compiler (since the configure test is apparently not finding |
300fd305 | 88 | all the compilers that will to crash and burn). |
bcb0a24a | 89 | |
fe2ef556 | 90 | - Fixed an issue in the md2man script when building from an alternate dir. |
bb484a79 | 91 | |
785cb938 | 92 | - Disable `--atimes` on macOS (it apparently just ignores the atime change). |
2e1b46db | 93 | |
bcb0a24a WD |
94 | ### ENHANCEMENTS: |
95 | ||
30945523 WD |
96 | - The use of `--backup-dir=STR` now implies `--backup`. |
97 | ||
98 | - Added `--zl=NUM` as a short-hand for `--compress-level=NUM`. | |
99 | ||
e16b2275 | 100 | - Added `--early-input=FILE` option that allows the client to send some |
f6df3708 | 101 | data to a daemon's (optional) "early exec" script on its stdin. |
e16b2275 | 102 | |
246d117d | 103 | - Mention atimes in the capabilities list that `--version` outputs. |
dfa34b47 WD |
104 | |
105 | - Mention either "default protect-args" or "optional protect-args" in the | |
106 | `--version` capabilities depending on how rsync was configured. | |
107 | ||
300fd305 | 108 | - Some info on optimizations is now elided from the `--version` capabilities |
246d117d WD |
109 | since they aren't really user-facing capabilities. You can still see the |
110 | info (plus the status of a couple extra optimizations) by repeating the | |
dfa34b47 | 111 | `--version` option (e.g. `-VV`). |
bcb0a24a | 112 | |
b51b0b32 WD |
113 | - Updated various URLs to be https instead of http. |
114 | ||
115 | - Some documentation improvements. | |
f4e6fe54 WD |
116 | |
117 | ### PACKAGING RELATED: | |
118 | ||
785cb938 | 119 | - If you had to use `--disable-simd` for 3.2.0, you might want to try removing |
246d117d WD |
120 | that and see if it will succeed or auto-disable. Some buggy clang++ |
121 | compilers are still not auto disabled, though. | |
f4e6fe54 WD |
122 | |
123 | - The MD5 asm code is now under its own configure flag (not shared with the | |
124 | SIMD setting), so if you have any issues compiling it, re-run configure with | |
125 | `--disable-asm`. | |
126 | ||
87bca719 WD |
127 | - Merged the OLDNEWS.md file into NEWS.md. |

132 | # NEWS for rsync 3.2.0 (19 Jun 2020) | |
133 | ||
134 | Protocol: 31 (unchanged) | |
135 | ||
136 | ## Changes since 3.1.3: | |
137 | ||
138 | ### BUG FIXES: | |
139 | ||
140 | - Avoid a potential out-of-bounds read in daemon mode if argc can be made to | |
141 | become 0. | |
142 | ||
143 | - Fix the default list of skip-compress files for non-daemon transfers. | |
144 | ||
145 | - Fix xattr filter rules losing an 'x' attribute in a non-local transfer. | |
146 | ||
147 | - Avoid an error when a check for a potential fuzzy file happens to reference | |
148 | a directory. | |
149 | ||
150 | - Make the atomic-rsync helper script have a more consistent error-exit. | |
151 | ||
300fd305 WD |
152 | - Make sure that a signal handler's use of exit_cleanup() calls `_exit()` |
153 | instead of exit(). | |
128139c6 WD |
154 | |
155 | - Various zlib fixes, including security fixes for CVE-2016-9843, | |
156 | CVE-2016-9842, CVE-2016-9841, and CVE-2016-9840. | |
157 | ||
158 | - Fixed an issue with `--remove-source-files` not removing a source symlink | |
159 | when combined with `--copy-links`. | |
160 | ||
161 | - Fixed a bug where the daemon would fail to write early fatal error messages | |
162 | to the client, such as refused or unknown command-line options. | |
163 | ||
164 | - Fixed the block-size validation logic when dealing with older protocols. | |
165 | ||
166 | - Some rrsync fixes and enhancements to handle the latest options. | |
167 | ||
168 | - Fixed a problem with the `--link-dest`|`--copy-dest` code when `--xattrs` | |
169 | was specified along with multiple alternate-destination directories (it | |
170 | could possibly choose a bad file match while trying to find a better xattr | |
171 | match). | |
172 | ||
173 | - Fixed a couple bugs in the handling of files with the `--sparse` option. | |
174 | ||
f6df3708 | 175 | - Fixed a bug in the writing of the batch.sh file (w/`--write-batch`) when the |
128139c6 WD |
176 | source & destination args were not last on the command-line. |
177 | ||
178 | - Avoid a hang when an overabundance of messages clogs up all the I/O buffers. | |
179 | ||
180 | - Fixed a mismatch in the RSYNC_PID values put into the environment of | |
181 | `pre-xfer exec` and a `post-xfer exec`. | |
182 | ||
183 | - Fixed a crash in the `--iconv` code. | |
184 | ||
185 | - Fixed a rare crash in the popt_unalias() code. | |
186 | ||
187 | ### ENHANCEMENTS: | |
188 | ||
189 | - Various checksum enhancements, including the optional use of openssl's MD4 & | |
190 | MD5 checksum algorithms, some x86-64 optimizations for the rolling checksum, | |
191 | some x86-64 optimizations for the (non-openssl) MD5 checksum, the addition | |
1bdf68b9 | 192 | of xxHash checksum support, and a negotiation heuristic that ensures that it |
128139c6 WD |
193 | is easier to add new checksum algorithms in the future. The environment |
194 | variable `RSYNC_CHECKSUM_LIST` can be used to customize the preference order | |
195 | of the negotiation, or use `--checksum-choice` (`--cc`) to force a choice. | |
196 | ||
197 | - Various compression enhancements, including the addition of zstd and lz4 | |
198 | compression algorithms and a negotiation heuristic that picks the best | |
199 | compression option supported by both sides. The environment variable | |
200 | `RSYNC_COMPRESS_LIST` can be used to customize the preference order of the | |
201 | negotiation, or use `--compress-choice` (`--zc`) to force a choice. | |
202 | ||
785cb938 | 203 | - Added a `--debug=NSTR` option that outputs details of the new negotiation |
128139c6 WD |
204 | strings (for checksums and compression). The first level just outputs the |
205 | result of each negotiation on the client, level 2 outputs the values of the | |
206 | strings that were sent to and received from the server, and level 3 outputs | |
207 | all those values on the server side too (when the server was given the debug | |
208 | option). | |
209 | ||
785cb938 | 210 | - The `--debug=OPTS` command-line option is no longer auto-forwarded to the |
128139c6 WD |
211 | remote rsync which allows for the client and server to have different levels |
212 | of debug specified. This also allows for newer debug options to be | |
785cb938 | 213 | specified, such as using `--debug=NSTR` to see the negotiated hash result, |
128139c6 | 214 | without having the command fail if the server version is too old to handle |
f6df3708 | 215 | that debug item. Use `-M--debug=OPTS` to send the options to the remote side. |
128139c6 WD |
216 | |
217 | - Added the `--atimes` option based on the long-standing patch (just with some | |
218 | fixes that the patch has been needing). | |
219 | ||
220 | - Added `--open-noatime` option to open files using `O_NOATIME`. | |
221 | ||
222 | - Added the `--write-devices` option based on the long-standing patch. | |
223 | ||
224 | - Added openssl & preliminary gnutls support to the rsync-ssl script, which is | |
225 | now installed by default. This was unified with the old stunnel-rsync | |
226 | helper script to simplify packaging. Note that the script accepts the use | |
785cb938 WD |
227 | of `--type=gnutls` for gnutls testing, but does not look for gnutls-cli on |
228 | the path yet. The use of `--type=gnutls` will not work right until | |
229 | gnutls-cli no longer drops data. | |
128139c6 WD |
230 | |
231 | - Rsync was enhanced to set the `RSYNC_PORT` environment variable when running | |
232 | a daemon-over-rsh script. Its value is the user-specified port number (set | |
233 | via `--port` or an rsync:// URL) or 0 if the user didn't override the port. | |
234 | ||
235 | - Added the `proxy protocol` daemon parameter that allows your rsyncd to know | |
236 | the real remote IP when it is setup behind a proxy. | |
237 | ||
238 | - Added negated matching to the daemon's `refuse options` setting by using | |
239 | match strings that start with a `!` (such as `!compress*`). This lets you | |
240 | refuse all options except for a particular approved list, for example. It | |
241 | also lets rsync refuse certain options by default (such as `write-devices`) | |
242 | while allowing the config to override that, as desired. | |
243 | ||
244 | - Added the `early exec` daemon parameter that runs a script before the | |
245 | transfer parameters are known, allowing some early setup based on module | |
246 | name. | |
247 | ||
248 | - Added status output in response to a signal (via both SIGINFO & SIGVTALRM). | |
249 | ||
250 | - Added `--copy-as=USER` option to give some extra security to root-run rsync | |
251 | commands into/from untrusted directories (such as backups and restores). | |
252 | ||
253 | - When resuming the transfer of a file in the `--partial-dir`, rsync will now | |
254 | update that partial file in-place instead of creating yet another tmp file | |
255 | copy. This requires both sender & receiver to be at least v3.2.0. | |
256 | ||
257 | - Added support for `RSYNC_SHELL` & `RSYNC_NO_XFER_EXEC` environment variables | |
258 | that affect the early, pre-xfer, and post-xfer exec rsync daemon parameters. | |
259 | ||
260 | - Optimize the `--fuzzy --fuzzy` heuristic to avoid the fuzzy directory scan | |
261 | until all other basis-file options are exhausted (such as `--link-dest`). | |
262 | ||
263 | - Have the daemon log include the normal-exit sent/received stats when the | |
264 | transfer exited with an error when possible (i.e. if it is the sender). | |
265 | ||
266 | - The daemon now locks its pid file (when configured to use one) so that it | |
267 | will not fail to start when the file exists but no daemon is running. | |
268 | ||
269 | - Various man page improvements, including some html representations (that | |
270 | aren't installed by default). | |
271 | ||
785cb938 | 272 | - Made `-V` the short option for `--version` and improved its information. |
128139c6 | 273 | |
785cb938 WD |
274 | - Pass the `-4` or `-6` option to the ssh command, making it easier to type |
275 | than `--rsh='ssh -4'` (or the `-6` equivalent). | |
128139c6 WD |
276 | |
277 | - Added example config for rsyncd SSL proxy configs to rsyncd.conf. | |
278 | ||
279 | - More errors messages now mention if the error is coming from the sender or | |
280 | the receiver. | |
281 | ||
282 | ### PACKAGING RELATED: | |
283 | ||
284 | - Add installed binary: /usr/bin/rsync-ssl | |
285 | ||
286 | - Add installed man page: /usr/man/man1/rsync-ssl.1 | |
287 | ||
87bca719 | 288 | - Tweak auxiliary doc file names, such as: README.md, INSTALL.md, & NEWS.md. |
128139c6 WD |
289 | |
290 | - The rsync-ssl script wants to run openssl or stunnel4, so consider adding a | |
291 | dependency for one of those options (though it's probably fine to just let | |
292 | it complain about being unable to find the program and let the user decide | |
293 | if they want to install one or the other). | |
294 | ||
295 | - If you packaged rsync + rsync-ssl + rsync-ssl-daemon as separate packages, | |
296 | the rsync-ssl package is now gone (rsync-ssl should be considered to be | |
297 | mainstream now that Samba requires SSL for its rsync daemon). | |
298 | ||
299 | - Add _build_ dependency for liblz4-dev, libxxhash-dev, libzstd-dev, and | |
300 | libssl-dev. These development libraries will give rsync extra compression | |
301 | algorithms, extra checksum algorithms, and allow use of openssl's crypto | |
302 | lib for (potentially) faster MD4/MD5 checksums. | |
303 | ||
304 | - Add _build_ dependency for g++ or clang++ on x86_64 systems to enable the | |
305 | SIMD checksum optimizations. | |
306 | ||
307 | - Add _build_ dependency for _either_ python3-cmarkcfm or python3-commonmark | |
308 | to allow for patching of man pages or building a git release. This is not | |
309 | required for a release-tar build, since it comes with pre-built man pages. | |
310 | Note that cmarkcfm is faster than commonmark, but they generate the same | |
311 | data. The commonmark dependency is easiest to install since it's native | |
785cb938 WD |
312 | python, and can even be installed via `pip3 install --user commonmark` if |
313 | you want to just install it for the build user. | |
128139c6 WD |
314 | |
315 | - Remove yodl _build_ dependency (if it was even listed before). | |
316 | ||
317 | ### DEVELOPER RELATED: | |
318 | ||
319 | - Silenced some annoying warnings about major() & minor() by improving an | |
320 | autoconf include-file check. | |
321 | ||
322 | - Converted the man pages from yodl to markdown. They are now processed via a | |
323 | simple python3 script using the cmarkgfm **or** commonmark library. This | |
324 | should make it easier to package rsync, since yodl has gotten obscure. | |
325 | ||
326 | - Improved some configure checks to work better with strict C99 compilers. | |
327 | ||
328 | - Some perl building/packaging scripts were recoded into awk and python3. | |
329 | ||
330 | - Some defines in byteorder.h were changed into static inline functions that | |
331 | will help to ensure that the args don't get evaluated multiple times on | |
332 | "careful alignment" hosts. | |
333 | ||
334 | - Some code typos were fixed (as pointed out by a Fossies run). | |

339 | # NEWS for rsync 3.1.3 (28 Jan 2018) | |
340 | ||
341 | Protocol: 31 (unchanged) | |
342 | ||
343 | ## Changes since 3.1.2: | |
344 | ||
345 | ### SECURITY FIXES: | |
346 | ||
347 | - Fixed a buffer overrun in the protocol's handling of xattr names and ensure | |
348 | that the received name is null terminated. | |
349 | ||
350 | - Fix an issue with `--protect-args` where the user could specify the arg in the | |
351 | protected-arg list and short-circuit some of the arg-sanitizing code. | |
352 | ||
353 | ### BUG FIXES: | |
354 | ||
355 | - Don't output about a new backup dir without appropriate info verbosity. | |
356 | ||
357 | - Fixed some issues with the sort functions in support/rsyncstats script. | |
358 | ||
359 | - Added a way to specify daemon config lists (e.g. users, groups, etc) that | |
360 | contain spaces (see `auth users` in the latest rsyncd.conf manpage). | |
361 | ||
362 | - If a backup fails (e.g. full disk) rsync exits with an error. | |
363 | ||
364 | - Fixed a problem with a doubled `--fuzzy` option combined with `--link-dest`. | |
365 | ||
366 | - Avoid invalid output in the summary if either the start or end time had an | |
367 | error. | |
368 | ||
369 | - We don't allow a popt alias to affect the `--daemon` or `--server` options. | |
370 | ||
371 | - Fix daemon exclude code to disallow attribute changes in addition to | |
372 | disallowing transfers. | |
373 | ||
374 | - Don't force nanoseconds to match if a non-transferred, non-checksummed file | |
375 | only passed the quick-check w/o comparing nanosecods. | |
376 | ||
377 | ### ENHANCEMENTS: | |
378 | ||
379 | - Added the ability for rsync to compare nanosecond times in its file-check | |
380 | comparisons, and added support nanosecond times on Mac OS X. | |
381 | ||
382 | - Added a short-option (`-@`) for `--modify-window`. | |
383 | ||
384 | - Added the `--checksum-choice=NAME[,NAME]` option to choose the checksum | |
385 | algorithms. | |
386 | ||
387 | - Added hashing of xattr names (with using `-X`) to improve the handling of | |
388 | files with large numbers of xattrs. | |
389 | ||
390 | - Added a way to filter xattr names using include/exclude/filter rules (see | |
391 | the `--xattrs` option in the manpage for details). | |
392 | ||
393 | - Added `daemon chroot|uid|gid` to the daemon config (in addition to the old | |
394 | chroot|uid|gid settings that affect the daemon's transfer process). | |
395 | ||
396 | - Added `syslog tag` to the daemon configuration. | |
397 | ||
398 | - Some manpage improvements. | |
399 | ||
400 | ### DEVELOPER RELATED: | |
401 | ||
402 | - Tweak the `make` output when yodl isn't around to create the man pages. | |
403 | ||
404 | - Changed an obsolete autoconf compile macro. | |
405 | ||
406 | - Support newer yodl versions when converting man pages. | |
407 | ||

411 | # NEWS for rsync 3.1.2 (21 Dec 2015) | |
412 | ||
413 | Protocol: 31 (unchanged) | |
414 | ||
415 | ## Changes since 3.1.1: | |
416 | ||
417 | ### SECURITY FIXES: | |
418 | ||
419 | - Make sure that all transferred files use only path names from inside the | |
420 | transfer. This makes it impossible for a malicious sender to try to make the | |
421 | receiver use an unsafe destination path for a transferred file, such as a | |
422 | just-sent symlink. | |
423 | ||
424 | ### BUG FIXES: | |
425 | ||
426 | - Change the checksum seed order in the per-block checksums. This prevents | |
427 | someone from trying to create checksum blocks that match in sum but not | |
428 | content. | |
429 | ||
430 | - Fixed a with the per-dir filter files (using `-FF`) that could trigger an | |
431 | assert failure. | |
432 | ||
433 | - Only skip `set_modtime()` on a transferred file if the time is exactly | |
434 | right. | |
435 | ||
436 | - Don't create an empty backup dir for a transferred file that doesn't exist | |
437 | yet. | |
438 | ||
439 | - Fixed a bug where `--link-dest` and `--xattrs` could cause rsync to exit if | |
440 | a filename had a matching dir of the same name in the alt-dest area. | |
441 | ||
442 | - Allow more than 32 group IDs per user in the daemon's gid=LIST config. | |
443 | ||
444 | - Fix the logging of %b & %c via `--log-file` (daemon logging was already | |
445 | correct, as was `--out-format='%b/%c'`). | |
446 | ||
447 | - Fix erroneous acceptance of `--info=5` & `--debug=5` (an empty flag name is | |
448 | not valid). | |
449 | ||
450 | ### ENHANCEMENTS: | |
451 | ||
452 | - Added `(DRY RUN)` info to the `--debug=exit` output line. | |
453 | ||
454 | - Use usleep() for our msleep() function if it is available. | |
455 | ||
456 | - Added a few extra long-option names to rrsync script, which will make | |
457 | BackupPC happier. | |
458 | ||
459 | - Made configure choose to use linux xattrs on netbsd (rather than not | |
460 | supporting xattrs). | |
461 | ||
462 | - Added `-wo` (write-only) option to rrsync support script. | |
463 | ||
464 | - Misc. manpage tweaks. | |
465 | ||
466 | ### DEVELOPER RELATED: | |
467 | ||
468 | - Fixed a bug with the Makefile's use of `INSTALL_STRIP`. | |
469 | ||
470 | - Improve a test in the suite that could get an erroneous timestamp error. | |
471 | ||
472 | - Tweaks for newer versions of git in the packaging tools. | |
473 | ||
474 | - Improved the m4 generation rules and some autoconf idioms. | |

479 | # NEWS for rsync 3.1.1 (22 Jun 2014) | |
480 | ||
481 | Protocol: 31 (unchanged) | |
482 | ||
483 | ## Changes since 3.1.0: | |
484 | ||
485 | ### BUG FIXES: | |
486 | ||
487 | - If the receiver gets bogus filenames from the sender (an unexpected leading | |
488 | slash or a `..` infix dir), exit with an error. This prevents a malicious | |
489 | sender from trying to inject filenames that would affect an area outside the | |
490 | destination directories. | |
491 | ||
492 | - Fixed a failure to remove the partial-transfer temp file when interrupted | |
493 | (and rsync is not saving the partial files). | |
494 | ||
495 | - Changed the chown/group/xattr-set order to avoid losing some security- | |
496 | related xattr info (that would get cleared by a chown). | |
497 | ||
498 | - Fixed a bug in the xattr-finding code that could make a non-root-run | |
499 | receiver not able to find some xattr numbers. | |
500 | ||
501 | - Fixed a bug in the early daemon protocol where a timeout failed to be | |
502 | honored (e.g. if the remote side fails to send us the initial protocol | |
503 | greeting). | |
504 | ||
505 | - Fixed unintended inclusion of commas in file numbers in the daemon log. | |
506 | ||
507 | - We once again send the 'f' sub-flag (of `-e`) to the server side so it knows | |
508 | that we can handle incremental-recursion directory errors properly in older | |
509 | protocols. | |
510 | ||
511 | - Fixed an issue with too-aggressive keep-alive messages causing a problem for | |
512 | older rsync versions early in the transfer. | |
513 | ||
514 | - Fixed an incorrect message about backup-directory-creation when using | |
515 | `--dry-run` and the backup dir is not an absolute path. | |
516 | ||
517 | - Fixed a bug where a failed deletion and/or a failed sender-side removal | |
518 | would not affect the exit code. | |
519 | ||
520 | - Fixed a bug that caused a failure when combining `--delete-missing-args` | |
521 | with `--xattrs` and/or `--acls`. | |
522 | ||
523 | - Fixed a strange `dir_depth` assertion error that was caused by empty-dir | |
524 | removals and/or duplicate files in the transfer. | |
525 | ||
526 | - Fixed a problem with `--info=progress2`'s output stats where rsync would | |
527 | only update the stats at the end of each file's transfer. It now uses the | |
528 | data that is flowing for the current file, making the stats more accurate | |
529 | and less jumpy. | |
530 | ||
531 | - Fixed an itemize bug that affected the combo of `--link-dest`, `-X`, and | |
532 | `-n`. | |
533 | ||
534 | - Fixed a problem with delete messages not appearing in the log file when the | |
535 | user didn't use `--verbose`. | |
536 | ||
537 | - Improve chunked xattr reading for OS X. | |
538 | ||
539 | - Removed an attempted hard-link xattr optimization that was causing a | |
540 | transfer failure. This removal is flagged in the compatibility code, so if a | |
541 | better fix can be discovered, we have a way to flip it on again. | |
542 | ||
543 | - Fixed a bug when the receiver is not configured to be able to hard link | |
544 | symlimks/devices/special-file items but the sender sent some of these items | |
545 | flagged as hard-linked. | |
546 | ||
547 | - We now generate a better error if the buffer overflows in `do_mknod()`. | |
548 | ||
549 | - Fixed a problem reading more than 16 ACLs on some OSes. | |
550 | ||
551 | - Fixed the reading of the secrets file to avoid an infinite wait when the | |
552 | username is missing. | |
553 | ||
554 | - Fixed a parsing problem in the `--usermap`/`--groupmap` options when using | |
555 | MIN-MAX numbers. | |
556 | ||
557 | - Switched Cygwin back to using socketpair `pipes` to try to speed it up. | |
558 | ||
559 | - Added knowledge of a few new options to rrsync. | |
560 | ||
561 | ### ENHANCEMENTS: | |
562 | ||
563 | - Tweaked the temp-file naming when `--temp-dir=DIR` is used: the temp-file | |
564 | names will not get a '.' prepended. | |
565 | ||
566 | - Added support for a new-compression idiom that does not compress all the | |
567 | matching data in a transfer. This can help rsync to use less cpu when a | |
568 | transfer has a lot of matching data, and also makes rsync compatible with a | |
569 | non-bundled zlib. See the `--new-compress` and `--old-compress` options in | |
570 | the manpage. | |
571 | ||
572 | - Added the support/rsync-no-vanished wrapper script. | |
573 | ||
574 | - Made configure more prominently mention when we failed to find yodl (in case | |
575 | the user wants to be able to generate manpages from `*.yo` files). | |
576 | ||
577 | - Have manpage mention how a daemon's max-verbosity setting affects info and | |
578 | debug options. Also added more clarification on backslash removals for | |
579 | excludes that contain wildcards. | |
580 | ||
581 | - Have configure check if for the attr lib (for getxattr) for those systems | |
582 | that need to link against it explicitly. | |
583 | ||
584 | - Change the early dir-creation logic to only use that idiom in an | |
585 | inc-recursive copy that is preserving directory times. e.g. using | |
586 | `--omit-dir-times` will avoid these early directories being created. | |
587 | ||
588 | - Fix a bug in `cmp_time()` that would return a wrong result if the 2 times | |
589 | differed by an amount greater than what a `time_t` can hold. | |
590 | ||
591 | ### DEVELOPER RELATED: | |
592 | ||
593 | - We now include an example systemd file (in packaging/systemd). | |
594 | ||
595 | - Tweaked configure to make sure that any intended use of the included popt | |
596 | and/or zlib code is put early in the CFLAGS. | |
597 | ||

601 | # NEWS for rsync 3.1.0 (28 Sep 2013) | |
602 | ||
603 | Protocol: 31 (changed) | |
604 | ||
605 | ## Changes since 3.0.9: | |
606 | ||
607 | ### OUTPUT CHANGES: | |
608 | ||
609 | - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the | |
610 | `--human-readable` option for a way to turn it off. See also the daemon's | |
611 | `log format` parameter and related command-line options (including | |
612 | `--out-format`) for a modifier that can be used to request digit-grouping or | |
613 | human-readable output in log escapes. (Note that log output is unchanged by | |
614 | default.) | |
615 | ||
616 | - The `--list-only` option is now affected by the `--human-readable` setting. | |
617 | It will display digit groupings by default, and unit suffixes if higher | |
618 | levels of readability are requested. Also, the column width for the size | |
619 | output has increased from 11 to 14 characters when human readability is | |
620 | enabled. Use `--no-h` to get the old-style output and column size. | |
621 | ||
622 | - The output of the `--progress` option has changed: the string `xfer` was | |
623 | shortened to `xfr`, and the string `to-check` was shortened to `to-chk`, | |
624 | both designed to make room for the (by default) wider display of file size | |
625 | numbers without making the total line-length longer. Also, when incremental | |
626 | recursion is enabled, the string `ir-chk` will be used instead of `to-chk` | |
627 | up until the incremental-recursion scan is done, letting you know that the | |
628 | value to check and the total value will still be increasing as new files are | |
629 | found. | |
630 | ||
631 | - Enhanced the `--stats` output: 1) to mention how many files were created | |
632 | (protocol >= 28), 2) to mention how many files were deleted (a new line for | |
633 | protocol 31, but only output when `--delete` is in effect), and 3) to follow | |
634 | the file-count, created-count, and deleted-count with a subcount list that | |
635 | shows the counts by type. The wording of the transferred count has also | |
636 | changed so that it is clearer that it is only a count of regular files. | |
637 | ||
638 | ### BUG FIXES: | |
639 | ||
640 | - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a full | |
641 | output buffer. | |
642 | ||
643 | - Fixed some rare bugs in `--iconv` processing that might cause a multibyte | |
644 | character to get translated incorrectly. | |
645 | ||
646 | - Fixed a bogus `vanished file` error if some files were specified with `./` | |
647 | prefixes and others were not. | |
648 | ||
649 | - Fixed a bug in `--sparse` where an extra gap could get inserted after a | |
650 | partial write. | |
651 | ||
652 | - Changed the way `--progress` overwrites its prior output in order to make it | |
653 | nearly impossible for the progress to get overwritten by an error. | |
654 | ||
655 | - Improved the propagation of abnormal-exit error messages. This should help | |
656 | the client side to receive errors from the server when it is exiting | |
657 | abnormally, and should also avoid dying with an `connection unexpectedly | |
658 | closed` exit when the closed connection is really expected. | |
659 | ||
660 | - The sender now checks each file it plans to remove to ensure that it hasn't | |
661 | changed from the first stat's info. This helps to avoid losing file data | |
662 | when the user is not using the option in a safe manner. | |
663 | ||
664 | - Fixed a data-duplication bug in the compress option that made compression | |
665 | less efficient. This improves protocol 31 onward, while behaving in a | |
666 | compatible (buggy) manner with older rsync protocols. | |
667 | ||
668 | - When creating a temp-file, rsync is now a bit smarter about it dot-char | |
669 | choices, which can fix a problem on OS X with names that start with `..`. | |
670 | ||
671 | - Rsync now sets a cleanup flag for `--inplace` and `--append` transfers that | |
672 | will flush the write buffer if the transfer aborts. This ensures that more | |
673 | received data gets written out to the disk on an aborted transfer (which is | |
674 | quite helpful on a slow, flaky connection). | |
675 | ||
676 | - The reads that `map_ptr()` now does are aligned on 1K boundaries. This helps | |
677 | some filesystems and/or files that don't like unaligned reads. | |
678 | ||
679 | - Fix an issue in the msleep() function if time jumps backwards. | |
680 | ||
681 | - Fix daemon-server module-name splitting bug where an arg would get split | |
682 | even if `--protect-args` was used. | |
683 | ||
684 | ### ENHANCEMENTS: | |
685 | ||
686 | - Added the `--remote-option=OPT` (`-M OPT`) command-line option that is | |
687 | useful for things like sending a remote `--log-file=FILE` or `--fake-super` | |
688 | option. | |
689 | ||
690 | - Added the `--info=FLAGS` and `--debug=FLAGS` options to allow finer-grained | |
691 | control over what is output. Added an extra type of `--progress` output | |
692 | using `--info=progress2`. | |
693 | ||
694 | - The `--msgs2stderr` option can help with debugging rsync by allowing the | |
695 | debug messages to get output to stderr rather than travel via the socket | |
696 | protocol. | |
697 | ||
698 | - Added the `--delete-missing-args` and `--ignore-missing-args` options to | |
699 | either delete or ignore user-specified files on the receiver that are | |
700 | missing on the sender (normally the absence of user-specified files | |
701 | generates an error). | |
702 | ||
703 | - Added a `T` (terabyte) category to the `--human-readable` size suffixes. | |
704 | ||
705 | - Added the `--usermap`/`--groupmap`/`--chown` options for manipulating file | |
706 | ownership during the copy. | |
707 | ||
708 | - Added the `%C` escape to the log-output handling, which will output the MD5 | |
709 | checksum of any transferred file, or all files if `--checksum` was specified | |
710 | (when protocol 30 or above is in effect). | |
711 | ||
712 | - Added the `reverse lookup` parameter to the rsync daemon config file to | |
713 | allow reverse-DNS lookups to be disabled. | |
714 | ||
715 | - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can be | |
716 | disabled via `forward lookup` parameter (defaults to enabled). | |
717 | ||
718 | - Added a way for more than one group to be specified in the daemon's config | |
719 | file, including a way to specify that you want all of the specified user's | |
720 | groups without having to name them. Also changed the daemon to complain | |
721 | about an inability to set explicitly-specified uid/gid values, even when not | |
722 | run by a super-user. | |
723 | ||
724 | - The daemon now tries to send the user the error messages from the pre-xfer | |
725 | exec script when it fails. | |
726 | ||
727 | - Improved the use of alt-dest options into an existing hierarchy of files: If | |
728 | a match is found in an alt-dir, it takes precedence over an existing file. | |
729 | (We'll need to wait for a future version before attribute-changes on | |
730 | otherwise unchanged files are safe when using an existing hierarchy.) | |
731 | ||
732 | - Added per-user authorization options and group-authorization support to the | |
733 | daemon's `auth users` parameter. | |
734 | ||
735 | - Added a way to reference environment variables in a daemon's config file | |
736 | (using %VAR% references). | |
737 | ||
738 | - When replacing a non-dir with a symlink/hard-link/device/special-file, the | |
739 | update should now be done in an atomic manner. | |
740 | ||
741 | - Avoid re-sending xattr info for hard-linked files w/the same xattrs | |
742 | (protocol 31). | |
743 | ||
744 | - The backup code was improved to use better logic maintaining the backup | |
745 | directory hierarchy. Also, when a file is being backed up, rsync tries to | |
746 | hard-link it into place so that the upcoming replacement of the destination | |
747 | file will be atomic (for the normal, non-inplace logic). | |
748 | ||
749 | - Added the ability to synchronize nano-second modified times. | |
750 | ||
751 | - Added a few more default suffixes for the `dont compress` settings. | |
752 | ||
753 | - Added the checking of the `RSYNC_PROTECT_ARGS` environment variable to allow | |
754 | the default for the `--protect-args` command-line option to be overridden. | |
755 | ||
756 | - Added the `--preallocate` command-line option. | |
757 | ||
758 | - Allow `--password-file=-` to read the password from stdin (filename `-`). | |
759 | ||
760 | - Rsync now comes packaged with an rsync-ssl helper script that can be used to | |
761 | contact a remote rsync daemon using a piped-stunnel command. It also | |
762 | includes an stunnel config file to run the server side to support ssl daemon | |
763 | connections. See the packaging/lsb/rsync.spec file for one way to package | |
764 | the resulting files. (Suggestions for how to make this even easier to | |
765 | install & use are welcomed.) | |
766 | ||
767 | - Improved the speed of some `--inplace` updates when there are lots of | |
768 | identical checksum blocks that end up being unusable. | |
769 | ||
770 | - Added the `--outbuf=N|L|B` option for choosing the output buffering. | |
771 | ||
772 | - Repeating the `--fuzzy` option now causes the code to look for fuzzy matches | |
773 | inside alt-dest directories too. | |
774 | ||
775 | - The `--chmod` option now supports numeric modes, e.g. `--chmod=644,D755` | |
776 | ||
777 | - Added some Solaris xattr code. | |
778 | ||
779 | - Made an rsync daemon (the listening process) exit with a 0 status when it | |
780 | was signaled to die. This helps launchd. | |
781 | ||
782 | - Improved the `RSYNC_*` environment variables for the pre-xfer exec script: | |
783 | when a daemon is sent multiple request args, they are now joined into a | |
784 | single return value (separated by spaces) so that the `RSYNC_REQUEST` | |
785 | environment variable is accurate for any `pre-xfer exec`. The values in | |
786 | `RSYNC_ARG#` vars are no longer truncated at the `.` arg (prior to the | |
787 | request dirs/files), so that all the requested values are also listed | |
788 | (separately) in `RSYNC_ARG#` variables. | |
789 | ||
790 | ### EXTRAS: | |
791 | ||
792 | - Added an `instant-rsyncd` script to the support directory, which makes it | |
793 | easy to configure a simple rsync daemon in the current directory. | |
794 | ||
795 | - Added the `mapfrom` and `mapto` scripts to the support directory, which | |
796 | makes it easier to do user/group mapping in a local transfer based on | |
797 | passwd/group files from another machine. | |
798 | ||
799 | - There's a new, improved version of the lsh script in the support dir: it's | |
800 | written in perl and supports `-u` without resorting to using sudo (when run | |
801 | as root). The old shell version is now named lsh.sh. | |
802 | ||
803 | - There is a helper script named rsync-slash-strip in the support directory | |
804 | for anyone that wants to change the way rsync handles args with trailing | |
805 | slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into | |
806 | arg/). | |
807 | ||
808 | ### INTERNAL: | |
809 | ||
810 | - The I/O code was rewritten to be simpler and do bigger buffered reads over | |
811 | the socket. The I/O between the receiver and the generator was changed to be | |
812 | standard multiplexed-I/O (like that over the socket). | |
813 | ||
814 | - The sender tries to use any dead time while the generator is looking for | |
815 | files to transfer in order to do sender-side directory scanning in a more | |
816 | parallel manner. | |
817 | ||
818 | - A daemon can now inform a client about a daemon-configured timeout value so | |
819 | that the client can assist in the keep-alive activity (protocol 31). | |
820 | ||
821 | - The filter code received some refactoring to make it more extendible, to | |
822 | read better, and do better sanity checking. | |
823 | ||
824 | - Really big numbers are now output using our own big-num routine rather than | |
825 | casting them to a double and using a %.0f conversion. | |
826 | ||
827 | - The `pool_alloc` library has received some minor improvements in alignment | |
828 | handling. | |
829 | ||
830 | - Added `init_stat_x()` function to avoid duplication of acl/xattr init code. | |
831 | ||
832 | - The included zlib was upgraded from 1.2.3 to 1.2.8. | |
833 | ||
834 | - Rsync can now be compiled to use an unmodified zlib library instead of the | |
835 | tweaked one that is included with rsync. This will eventually become the | |
836 | default, at which point we'll start the countdown to removing the included | |
837 | zlib. Until then, feel free to configure using: | |
838 | ||
839 | ./configure `--with-included-zlib=no` | |
840 | ||
841 | ### DEVELOPER RELATED: | |
842 | ||
843 | - Added more conditional debug output. | |
844 | ||
845 | - Fixed some build issues for android and minix. | |

850 | # NEWS for rsync 3.0.9 (23 Sep 2011) | |
851 | ||
852 | Protocol: 30 (unchanged) | |
853 | ||
854 | ## Changes since 3.0.8: | |
855 | ||
856 | ### BUG FIXES: | |
857 | ||
858 | - Fix a crash bug in checksum scanning when `--inplace` is used. | |
859 | ||
860 | - Fix a hang if a hard-linked file cannot be opened by the sender (e.g. if it | |
861 | has no read permission). | |
862 | ||
863 | - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux. | |
864 | ||
865 | - Fix a memory leak in the xattr code. | |
866 | ||
867 | - Fixed a bug with `--delete-excluded` when a filter merge file has a rule | |
868 | that specifies a receiver-only side restriction. | |
869 | ||
870 | - Fix a bug with the modifying of unwritable directories. | |
871 | ||
872 | - Fix `--fake-super`'s interaction with `--link-dest` same-file comparisons. | |
873 | ||
874 | - Fix the updating of the `curr_dir` buffer to avoid a duplicate slash. | |
875 | ||
876 | - Fix the directory permissions on an implied dot-dir when using `--relative` | |
877 | (e.g. /outside/path/././send/path). | |
878 | ||
879 | - Fixed some too-long sleeping instances when using `--bwlimit`. | |
880 | ||
881 | - Fixed when symlink ownership difference-checking gets compiled into | |
882 | `unchanged_attrs()`. | |
883 | ||
884 | - Improved the socket-error reporting when multiple protocols fail. | |
885 | ||
886 | - Fixed a case where a socket error could reference just-freed memory. | |
887 | ||
888 | - Failing to use a password file that was specified on the command-line is now | |
889 | a fatal error. | |
890 | ||
891 | - Fix the non-root updating of directories that don't have the read and/or | |
892 | execute permission. | |
893 | ||
894 | - Make daemon-excluded file errors more error-like. | |
895 | ||
896 | - Fix a compilation issue on older C compilers (due to a misplaced var | |
897 | declaration). | |
898 | ||
899 | - Make configure avoid finding socketpair on cygwin. | |
900 | ||
901 | - Avoid trying to reference `SO_BROADCAST` if the OS doesn't support it. | |
902 | ||
903 | - Fix some issues with the post-processing of the man pages. | |
904 | ||
905 | - Fixed the user home-dir handling in the support/lsh script. | |
906 | ||
907 | - Some minor manpage improvements. | |

912 | # NEWS for rsync 3.0.8 (26 Mar 2011) | |
913 | ||
914 | Protocol: 30 (unchanged) | |
915 | ||
916 | ## Changes since 3.0.7: | |
917 | ||
918 | ### BUG FIXES: | |
919 | ||
920 | - Fixed two buffer-overflow issues: one where a directory path that is exactly | |
921 | MAXPATHLEN was not handled correctly, and one handling a `--backup-dir` that | |
922 | is extra extra large. | |
923 | ||
924 | - Fixed a data-corruption issue when preserving hard-links without preserving | |
925 | file ownership, and doing deletions either before or during the transfer | |
926 | (CVE-2011-1097). This fixes some assert errors in the hard-linking code, and | |
927 | some potential failed checksums (via `-c`) that should have matched. | |
928 | ||
929 | - Fixed a potential crash when an rsync daemon has a filter/exclude list and | |
930 | the transfer is using ACLs or xattrs. | |
931 | ||
932 | - Fixed a hang if a really large file is being processed by an rsync that | |
933 | can't handle 64-bit numbers. Rsync will now complain about the file being | |
934 | too big and skip it. | |
935 | ||
936 | - For devices and special files, we now avoid gathering useless ACL and/or | |
937 | xattr information for files that aren't being copied. (The un-copied files | |
938 | are still put into the file list, but there's no need to gather data that is | |
939 | not going to be used.) This ensures that if the user uses `--no-D`, that | |
940 | rsync can't possibly complain about being unable to gather extended | |
941 | information from special files that are in the file list (but not in the | |
942 | transfer). | |
943 | ||
944 | - Properly handle requesting remote filenames that start with a dash. This | |
945 | avoids a potential error where a filename could be interpreted as a (usually | |
946 | invalid) option. | |
947 | ||
948 | - Fixed a bug in the comparing of upper-case letters in file suffixes for | |
949 | `--skip-compress`. | |
950 | ||
951 | - If an rsync daemon has a module configured without a path setting, rsync | |
952 | will now disallow access to that module. | |
953 | ||
954 | - If the destination arg is an empty string, it will be treated as a reference | |
955 | to the current directory (as 2.x used to do). | |
956 | ||
957 | - If rsync was compiled with a newer time-setting function (such as lutimes), | |
958 | rsync will fall-back to an older function (such as utimes) on a system where | |
959 | the newer function is not around. This helps to make the rsync binary more | |
960 | portable in mixed-OS-release situations. | |
961 | ||
962 | - Fixed a batch-file writing bug that would not write out the full set of | |
963 | compatibility flags that the transfer was using. This fixes a potential | |
964 | protocol problem for a batch file that contains a sender-side I/O error: it | |
965 | would have been sent in a way that the batch-reader wasn't expecting. | |
966 | ||
967 | - Some improvements to the hard-linking code to ensure that device-number | |
968 | hashing is working right, and to supply more information if the hard-link | |
969 | code fails. | |
970 | ||
971 | - The `--inplace` code was improved to not search for an impossible checksum | |
972 | position. The quadruple-verbose chunk[N] message will now mention when an | |
973 | inplace chunk was handled by a seek rather than a read+write. | |
974 | ||
975 | - Improved ACL mask handling, e.g. for Solaris. | |
976 | ||
977 | - Fixed a bug that prevented `--numeric-ids` from disabling the translation of | |
978 | user/group IDs for ACLs. | |
979 | ||
980 | - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest | |
981 | option (e.g. `--link-dest`) could output an error trying to itemize the | |
982 | changes against the alt-dest directory's xattr/ACL info but was instead | |
983 | trying to access the not-yet-existing new destination directory. | |
984 | ||
985 | - Improved xattr system-error messages to mention the full path to the file. | |
986 | ||
987 | - The `--link-dest` checking for identical symlinks now avoids considering | |
988 | attribute differences that cannot be changed on the receiver. | |
989 | ||
990 | - Avoid trying to read/write xattrs on certain file types for certain OSes. | |
991 | Improved configure to set `NO_SYMLINK_XATTRS`, `NO_DEVICE_XATTRS`, and/or | |
992 | `NO_SPECIAL_XATTRS` defines in config.h. | |
993 | ||
994 | - Improved the unsafe-symlink errors messages. | |
995 | ||
996 | - Fixed a bug setting xattrs on new files that aren't user writable. | |
997 | ||
998 | - Avoid re-setting xattrs on a hard-linked file w/the same xattrs. | |
999 | ||
1000 | - Fixed a bug with `--fake-super` when copying files and dirs that aren't user | |
1001 | writable. | |
1002 | ||
1003 | - Fixed a bug where a sparse file could have its last sparse block turned into | |
1004 | a real block when rsync sets the file size (requires ftruncate). | |
1005 | ||
1006 | - If a temp-file name is too long, rsync now avoids truncating the name in the | |
1007 | middle of adjacent high-bit characters. This prevents a potential filename | |
1008 | error if the filesystem doesn't allow a name to contain an invalid | |
1009 | multi-byte sequence. | |
1010 | ||
1011 | - If a muli-protocol socket connection fails (i.e., when contacting a daemon), | |
1012 | we now report all the failures, not just the last one. This avoids losing a | |
1013 | relevant error (e.g. an IPv4 connection-refused error) that happened before | |
1014 | the final error (e.g. an IPv6 protocol-not-supported error). | |
1015 | ||
1016 | - Generate a transfer error if we try to call chown with a `-1` for a uid or a | |
1017 | gid (which is not settable). | |
1018 | ||
1019 | - Fixed the working of `--force` when used with `--one-file-system`. | |
1020 | ||
1021 | - Fix the popt arg parsing so that an option that doesn't take an arg will | |
1022 | reject an attempt to supply one (can configure `--with-included-popt` if | |
1023 | your system's popt library doesn't yet have this fix). | |
1024 | ||
1025 | - A couple minor option tweaks to the support/rrsync script, and also some | |
1026 | regex changes that make vim highlighting happier. | |
1027 | ||
1028 | - Fixed some issues in the support/mnt-excl script. | |
1029 | ||
1030 | - Various manpage improvements. | |
1031 | ||
1032 | ### ENHANCEMENTS: | |
1033 | ||
1034 | - Added `.hg/` to the default cvs excludes (see `-C` & `--cvs-exclude`). | |
1035 | ||
1036 | ### DEVELOPER RELATED: | |
1037 | ||
1038 | - Use lchmod() whenever it is available (not just on symlinks). | |
1039 | ||
1040 | - A couple fixes to the `socketpair_tcp()` routine. | |
1041 | ||
1042 | - Updated the helper scripts in the packaging subdirectory. | |
1043 | ||
1044 | - Renamed configure.in to configure.ac. | |
1045 | ||
1046 | - Fixed configure's checking for iconv routines for newer OS X versions. | |
1047 | ||
1048 | - Fixed the testsuite/xattrs.test script on OS X. | |
1049 | ||

1053 | # NEWS for rsync 3.0.7 (31 Dec 2009) | |
1054 | ||
1055 | Protocol: 30 (unchanged) | |
1056 | ||
1057 | ## Changes since 3.0.6: | |
1058 | ||
1059 | ### BUG FIXES: | |
1060 | ||
1061 | - Fixed a bogus free when using `--xattrs` with `--backup`. | |
1062 | ||
1063 | - Avoid an error when `--dry-run` was trying to stat a prior hard-link file | |
1064 | that hasn't really been created. | |
1065 | ||
1066 | - Fixed a problem with `--compress` (`-z`) where the receiving side could | |
1067 | return the error "inflate (token) returned -5". | |
1068 | ||
1069 | - Fixed a bug where `--delete-during` could delete in a directory before it | |
1070 | noticed that the sending side sent an I/O error for that directory (both | |
1071 | sides of the transfer must be at least 3.0.7). | |
1072 | ||
1073 | - Improved `--skip-compress`'s error handling of bad character-sets and got | |
1074 | rid of a lingering debug fprintf(). | |
1075 | ||
1076 | - Fixed the daemon's conveyance of `io_error` value from the sender. | |
1077 | ||
1078 | - An rsync daemon use seteuid() (when available) if it used setuid(). | |
1079 | ||
1080 | - Get the permissions right on a `--fake-super` transferred directory that | |
1081 | needs more owner permissions to emulate root behavior. | |
1082 | ||
1083 | - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses its | |
1084 | modifier when sending the filter rules to the remote rsync. | |
1085 | ||
1086 | - Improved the "--delete does not work without -r or -d" message. | |
1087 | ||
1088 | - Improved rsync's handling of `--timeout` to avoid a weird timeout case where | |
1089 | the sender could timeout even though it has recently written data to the | |
1090 | socket (but hasn't read data recently, due to the writing). | |
1091 | ||
1092 | - Some misc manpage improvements. | |
1093 | ||
1094 | - Fixed the chmod-temp-dir testsuite on a system without /var/tmp. | |
1095 | ||
1096 | - Make sure that a timeout specified in the daemon's config is used as a | |
1097 | maximum timeout value when the user also specifies a timeout. | |
1098 | ||
1099 | - Improved the error-exit reporting when rsync gets an error trying to cleanup | |
1100 | after an error: the initial error is reported. | |
1101 | ||
1102 | - Improved configure's detection of IPv6 for solaris and cygwin. | |
1103 | ||
1104 | - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing. | |
1105 | ||
1106 | - Made our (only used if missing) getaddrinfo() routine use `inet_pton()` | |
1107 | (which we also provide) instead of `inet_aton()`. | |
1108 | ||
1109 | - The exit-related debug messages now mention the program's role so it is | |
1110 | clear who output what message. | |
1111 | ||
1112 | ### DEVELOPER RELATED: | |
1113 | ||
1114 | - Got rid of type-punned compiler warnings output by newer gcc versions. | |
1115 | ||
1116 | - The Makefile now ensures that proto.h will be rebuilt if config.h changes. | |
1117 | ||
1118 | - The testsuite no longer uses `id -u`, so it works better on solaris. | |
1119 | ||

1122 | ||
1123 | # NEWS for rsync 3.0.6 (8 May 2009) | |
1124 | ||
1125 | Protocol: 30 (unchanged) | |
1126 | ||
1127 | ## Changes since 3.0.5: | |
1128 | ||
1129 | ### BUG FIXES: | |
1130 | ||
1131 | - Fixed a `--read-batch` hang when rsync is reading a batch file that was | |
1132 | created from an incremental-recursion transfer. | |
1133 | ||
1134 | - Fixed the daemon's socket code to handle the simultaneous arrival of | |
1135 | multiple connections. | |
1136 | ||
1137 | - Fix `--safe-links`/`--copy-unsafe-links` to properly handle symlinks that | |
1138 | have consecutive slashes in the value. | |
1139 | ||
1140 | - Fixed the parsing of an `[IPv6_LITERAL_ADDR]` when a USER@ is prefixed. | |
1141 | ||
1142 | - The sender now skips a (bogus) symlink that has a 0-length value, which | |
1143 | avoids a transfer error in the receiver. | |
1144 | ||
1145 | - Fixed a case where the sender could die with a tag-0 error if there was an | |
1146 | I/O during the sending of the file list. | |
1147 | ||
1148 | - Fixed the rrsync script to avoid a server-side problem when `-e` is at the | |
1149 | start of the short options. | |
1150 | ||
1151 | - Fixed a problem where a vanished directory could turn into an exit code 23 | |
1152 | instead of the proper exit code 24. | |
1153 | ||
1154 | - Fixed the `--iconv` conversion of symlinks when doing a local copy. | |
1155 | ||
1156 | - Fixed a problem where `--one-file-system` was not stopping deletions on the | |
1157 | receiving side when a mount-point directory did not match a directory in the | |
1158 | transfer. | |
1159 | ||
1160 | - Fixed the dropping of an ACL mask when no named ACL values were present. | |
1161 | ||
1162 | - Fixed an ACL/xattr corruption issue where the `--backup` option could cause | |
1163 | rsync to associate the wrong ACL/xattr information with received files. | |
1164 | ||
1165 | - Fixed the use of `--xattrs` with `--only-write-batch`. | |
1166 | ||
1167 | - Fixed the use of `--dry-run` with `--read-batch`. | |
1168 | ||
1169 | - Fixed configure's erroneous use of target. | |
1170 | ||
1171 | - Fixed configure's `--disable-debug` option. | |
1172 | ||
1173 | - Fixed a run-time issue for systems that can't find `iconv_open()` by adding | |
1174 | the `--disable-iconv-open` configure option. | |
1175 | ||
1176 | - Complain and die if the user tries to combine `--remove-source-files` (or | |
1177 | the deprecated `--remove-sent-files`) with `--read-batch`. | |
1178 | ||
1179 | - Fixed an failure transferring special files from Solaris to Linux. | |
1180 | ||

1184 | # NEWS for rsync 3.0.5 (28 Dec 2008) | |
1185 | ||
1186 | Protocol: 30 (unchanged) | |
1187 | ||
1188 | ## Changes since 3.0.4: | |
1189 | ||
1190 | ### BUG FIXES: | |
1191 | ||
1192 | - Initialize xattr data in a couple spots in the hlink code, which avoids a | |
1193 | crash when the xattr pointer's memory happens to start out non-zero. Also | |
1194 | fixed the itemizing of an alt-dest file's xattrs when hard-linking. | |
1195 | ||
1196 | - Don't send a bogus `-` option to an older server if there were no short | |
1197 | options specified. | |
1198 | ||
1199 | - Fixed skipping of unneeded updates in a batch file when incremental | |
1200 | recursion is active. Added a test for this. Made batch-mode handle `redo` | |
1201 | files properly (and without hanging). | |
1202 | ||
1203 | - Fix the %P logfile escape when the daemon logs from inside a chroot. | |
1204 | ||
1205 | - Fixed the use of `-s` (`--protect-args`) when used with a remote source or | |
1206 | destination that had an empty path (e.g. `host:`). Also fixed a problem when | |
1207 | `-s` was used when accessing a daemon via a remote-shell. | |
1208 | ||
1209 | - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a `--files-from` | |
1210 | file when the root of the transfer isn't the current directory. | |
1211 | ||
1212 | - Fixed a bug with `-K --delete` removing symlinks to directories when | |
1213 | incremental recursion is active. | |
1214 | ||
1215 | - Fixed a hard to trigger hang when using `--remove-source-files`. | |
1216 | ||
1217 | - Got rid of an annoying delay when accessing a daemon via a remote-shell. | |
1218 | ||
1219 | - Properly ignore (superfluous) source args on a `--read-batch` command. | |
1220 | ||
1221 | - Improved the manpage's description of the `*` wildcard to remove the | |
1222 | confusing `non-empty` qualifier. | |
1223 | ||
1224 | - Fixed reverse lookups in the compatibility-library version of getnameinfo(). | |
1225 | ||
1226 | - Fixed a bug when using `--sparse` on a sparse file that has over 2GB of | |
1227 | consecutive sparse data. | |
1228 | ||
1229 | - Avoid a hang when using at least 3 `--verbose` options on a transfer with a | |
1230 | client sender (which includes local copying). | |
1231 | ||
1232 | - Fixed a problem with `--delete-delay` reporting an error when it was ready | |
1233 | to remove a directory that was now gone. | |
1234 | ||
1235 | - Got rid of a bunch of `warn_unused_result` compiler warnings. | |
1236 | ||
1237 | - If an ftruncate() on a received file fails, it now causes a partial- | |
1238 | transfer warning. | |
1239 | ||
1240 | - Allow a path with a leading `//` to be preserved (CYGWIN only). | |
1241 | ||
1242 | ### ENHANCEMENTS: | |
1243 | ||
1244 | - Made the support/atomic-rsync script able to perform a fully atomic update | |
1245 | of the copied hierarchy when the destination is setup using a particular | |
1246 | symlink idiom. | |
1247 | ||

1250 | ||
1251 | # NEWS for rsync 3.0.4 (6 Sep 2008) | |
1252 | ||
1253 | Protocol: 30 (unchanged) | |
1254 | ||
1255 | ## Changes since 3.0.3: | |
1256 | ||
1257 | ### BUG FIXES: | |
1258 | ||
1259 | - Fixed a bug in the hard-linking code where it would sometimes try to | |
1260 | allocate 0 bytes of memory (which fails on some OSes, such as AIX). | |
1261 | ||
1262 | - Fixed the hard-linking of files from a device that has a device number of 0 | |
1263 | (which seems to be a common device number on NetBSD). | |
1264 | ||
1265 | - Fixed the handling of a `--partial-dir` that cannot be created. This | |
1266 | particularly impacts the `--delay-updates` option (since the files cannot be | |
1267 | delayed without a partial-dir), and was potentially destructive if the | |
1268 | `--remove-source-files` was also specified. | |
1269 | ||
1270 | - Fixed a couple issues in the `--fake-super` handling of xattrs when the | |
1271 | destination files have root-level attributes (e.g. selinux values) that a | |
1272 | non-root copy can't affect. | |
1273 | ||
1274 | - Improved the keep-alive check in the generator to fire consistently in | |
1275 | incremental-recursion mode when `--timeout` is enabled. | |
1276 | ||
1277 | - The `--iconv` option now converts the content of a symlink too, instead of | |
1278 | leaving it in the wrong character-set (requires 3.0.4 on both sides of the | |
1279 | transfer). | |
1280 | ||
1281 | - When using `--iconv`, if a filename fails to convert on the receiving side, | |
1282 | this no longer makes deletions in the root-dir of the transfer fail silently | |
1283 | (the user now gets a warning about deletions being disabled due to IO error | |
1284 | as long as `--ignore-errors` was not specified). | |
1285 | ||
1286 | - When using `--iconv`, if a server-side receiver can't convert a filename, | |
1287 | the error message sent back to the client no longer mangles the name with | |
1288 | the wrong charset conversion. | |
1289 | ||
1290 | - Fixed a potential alignment issue in the IRIX ACL code when allocating the | |
1291 | initial `struct acl` object. Also, cast mallocs to avoid warnings. | |
1292 | ||
1293 | - Changed some errors that were going to stdout to go to stderr. | |
1294 | ||
1295 | - Made `human_num()` and `human_dnum()` able to output a negative number | |
1296 | (rather than outputting a cryptic string of punctuation). | |
1297 | ||
1298 | ### ENHANCEMENTS: | |
1299 | ||
1300 | - Rsync will avoid sending an `-e` option to the server if an older protocol | |
1301 | is requested (and thus the option would not be useful). This lets the user | |
1302 | specify the `--protocol=29` option to access an overly-restrictive server | |
1303 | that is rejecting the protocol-30 use of `-e` to the server. | |
1304 | ||
1305 | - Improved the message output for an `RERR_PARTIAL` exit. | |
1306 | ||
1307 | ### DEVELOPER RELATED: | |
1308 | ||
1309 | - The Makefile will not halt for just a timestamp change on the Makefile or | |
1310 | the configure files, only for actual changes in content. | |
1311 | ||
1312 | - Changed some commands in the testsuite's xattrs.test that called `rsync` | |
1313 | instead of `$RSYNC`. | |
1314 | ||
1315 | - Enhanced the release scripts to be able to handle a branch release and to do | |
1316 | even more consistency checks on the files. | |

1321 | # NEWS for rsync 3.0.3 (29 Jun 2008) | |
1322 | ||
1323 | Protocol: 30 (unchanged) | |
1324 | ||
1325 | ## Changes since 3.0.2: | |
1326 | ||
1327 | ### BUG FIXES: | |
1328 | ||
1329 | - Fixed a wildcard matching problem in the daemon when a module has `use | |
1330 | chroot` enabled. | |
1331 | ||
1332 | - Fixed a crash bug in the hard-link code. | |
1333 | ||
1334 | - Fixed the sending of xattr directory information when the code finds a | |
1335 | `--link-dest` or `--copy-dest` directory with unchanged xattrs -- the | |
1336 | destination directory now gets these unchanged xattrs properly applied. | |
1337 | ||
1338 | - Fixed an xattr-sending glitch that could cause an `Internal abbrev` error. | |
1339 | ||
1340 | - Fixed the combination of `--xattrs` and `--backup`. | |
1341 | ||
1342 | - The generator no longer allows a '.' dir to be excluded by a daemon- exclude | |
1343 | rule. | |
1344 | ||
1345 | - Fixed deletion handling when copying a single, empty directory (with no | |
1346 | files) to a differently named, non-existent directory. | |
1347 | ||
1348 | - Fixed the conversion of spaces into dashes in the %M log escape. | |
1349 | ||
1350 | - Fixed several places in the code that were not returning the right errno | |
1351 | when a function failed. | |
1352 | ||
1353 | - Fixed the backing up of a device or special file into a backup dir. | |
1354 | ||
1355 | - Moved the setting of the socket options prior to the connect(). | |
1356 | ||
1357 | - If rsync exits in the middle of a `--progress` output, it now outputs a | |
1358 | newline to help prevent the progress line from being overwritten. | |
1359 | ||
1360 | - Fixed a problem with how a destination path with a trailing slash or a | |
1361 | trailing dot-dir was compared against the daemon excludes. | |
1362 | ||
1363 | - Fixed the sending of large (size > 16GB) files when talking to an older | |
1364 | rsync (protocols < 30): we now use a compatible block size limit. | |
1365 | ||
1366 | - If a file's length is so huge that we overflow a checksum buffer count (i.e. | |
1367 | several hundred TB), warn the user and avoid sending an invalid checksum | |
1368 | struct over the wire. | |
1369 | ||
1370 | - If a source arg is excluded, `--relative` no longer adds the excluded arg's | |
1371 | implied dirs to the transfer. This fix also made the exclude check happen in | |
1372 | the better place in the sending code. | |
1373 | ||
1374 | - Use the `overflow_exit()` function for overflows, not `out_of_memory()`. | |
1375 | ||
1376 | - Improved the code to better handle a system that has only 32-bit file | |
1377 | offsets. | |
1378 | ||
1379 | ### ENHANCEMENTS: | |
1380 | ||
1381 | - The rsyncd.conf manpage now consistently refers to the parameters in the | |
1382 | daemon config file as `parameters`. | |
1383 | ||
1384 | - The description of the `--inplace` option was improved. | |
1385 | ||
1386 | ### EXTRAS: | |
1387 | ||
1388 | - Added a new script in the support directory, deny-rsync, which allows an | |
1389 | admin to (temporarily) replace the rsync command with a script that sends an | |
1390 | error message to the remote client via the rsync protocol. | |
1391 | ||
1392 | ### DEVELOPER RELATED: | |
1393 | ||
1394 | - Fixed a testcase failure if the tests are run as root and made some | |
1395 | compatibility improvements. | |
1396 | ||
1397 | - Improved the daemon tests, including checking module comments, the listing | |
1398 | of files, and the ensuring that daemon excludes can't affect a dot-dir arg. | |
1399 | ||
1400 | - Improved some build rules for those that build in a separate directory from | |
1401 | the source, including better install rules for the man pages, and the fixing | |
1402 | of a proto.h-tstamp rule that could make the binaries get rebuild without | |
1403 | cause. | |
1404 | ||
1405 | - Improved the testsuite to work around a problem with some utilities (e.g. cp | |
1406 | -p & touch -r) rounding sub-second timestamps. | |
1407 | ||
1408 | - Ensure that the early patches don't cause any generated-file hunks to | |
1409 | bleed-over into patches that follow. | |

1415 | ||
1416 | Protocol: 30 (unchanged) | |
1417 | ||
1418 | ## Changes since 3.0.1: | |
1419 | ||
1420 | ### BUG FIXES: | |
1421 | ||
1422 | - Fixed a potential buffer overflow in the xattr code. | |
1423 | ||
1424 | ### ENHANCEMENTS: | |
1425 | ||
1426 | - None. | |
1427 | ||
1428 | ### DEVELOPER RELATED: | |
1429 | ||
1430 | - The RPM spec file was improved to install more useful files. | |
1431 | ||
1432 | - A few developer-oriented scripts were moved from the support dir to the | |
1433 | packaging dir. | |

1438 | # NEWS for rsync 3.0.1 (3 Apr 2008) | |
1439 | ||
1440 | Protocol: 30 (unchanged) | |
1441 | ||
1442 | ## Changes since 3.0.0: | |
1443 | ||
1444 | ### NOTABLE CHANGES IN BEHAVIOR: | |
1445 | ||
1446 | - Added the 'c'-flag to the itemizing of non-regular files so that the | |
1447 | itemized output doesn't get hidden if there were no attribute changes, and | |
1448 | also so that the itemizing of a `--copy-links` run will distinguish between | |
1449 | copying an identical non-regular file and the creation of a revised version | |
1450 | with a new value (e.g. a changed symlink referent, a new device number, | |
1451 | etc.). | |
1452 | ||
1453 | ### BUG FIXES: | |
1454 | ||
1455 | - Fixed a crash bug when a single-use rsync daemon (via remote shell) was run | |
1456 | without specifying a `--config=FILE` option. | |
1457 | ||
1458 | - Fixed a crash when backing up a directory that has a default ACL. | |
1459 | ||
1460 | - Fixed a bug in the handling of xattr values that could cause rsync to not | |
1461 | think that a file's extended attributes are up-to-date. | |
1462 | ||
1463 | - Fixed the working of `--fake-super` with `--link-dest` and `--xattrs`. | |
1464 | ||
1465 | - Fixed a hang when combining `--dry-run` with `--remove-source-files`. | |
1466 | ||
1467 | - Fixed a bug with `--iconv`'s handling of files that cannot be converted: a | |
1468 | failed name can no longer cause a transfer failure. | |
1469 | ||
1470 | - Fixed the building of the rounding.h file on systems that need custom | |
1471 | CPPFLAGS to be used. Also improved the error reporting if the building of | |
1472 | rounding.h fails. | |
1473 | ||
1474 | - Fixed the use of the `--protect-args` (`-s`) option when talking to a | |
1475 | daemon. | |
1476 | ||
1477 | - Fixed the `--ignore-existing` option's protection of files on the receiver | |
1478 | that are non-regular files on the sender (e.g. if a symlink or a dir on the | |
1479 | sender is trying to replace a file on the receiver). The reverse protection | |
1480 | (protecting a dir/symlink/device from being replaced by a file) was already | |
1481 | working. | |
1482 | ||
1483 | - Fixed an assert failure if `--hard-links` is combined with an option that | |
1484 | can skip a file in a set of hard-linked files (i.e. `--ignore-existing`, | |
1485 | `--append`, etc.), without skipping all the files in the set. | |
1486 | ||
1487 | - Avoid setting the modify time on a directory that already has the right | |
1488 | modify time set. This avoids tweaking the dir's ctime. | |
1489 | ||
1490 | - Improved the daemon-exclude handling to do a better job of applying the | |
1491 | exclude rules to path entries. It also sends the user an error just as if | |
1492 | the files were actually missing (instead of silently ignoring the user's | |
1493 | args), and avoids sending the user the filter-action messages for these | |
1494 | non-user-initiated rules. | |
1495 | ||
1496 | - Fixed some glitches with the dry-run code's missing-directory handling, | |
1497 | including a problem when combined with `--fuzzy`. | |
1498 | ||
1499 | - Fixed some glitches with the skipped-directory handling. | |
1500 | ||
1501 | - Fixed the 'T'-flag itemizing of symlinks when `--time` isn't preserved. | |
1502 | ||
1503 | - Fixed a glitch in the itemizing of permissions with the `-E` option. | |
1504 | ||
1505 | - The `--append` option's restricting of transfers to those that add data no | |
1506 | longer prevents the updating of non-content changes to otherwise up-to- date | |
1507 | files (i.e. those with the same content but differing permissions, | |
1508 | ownership, xattrs, etc.). | |
1509 | ||
1510 | - Don't allow `--fake-super` to be specified with `-XX` (double `--xattrs`) | |
1511 | because the options conflict. If a daemon has `fake super` enabled, it | |
1512 | automatically downgrades a `-XX` request to `-X`. | |
1513 | ||
1514 | - Fixed a couple bugs in the parsing of daemon-config excludes that could make | |
1515 | a floating exclude rule get treated as matching an absolute path. | |
1516 | ||
1517 | - A daemon doesn't try to auto-refuse the `iconv` option if iconv-support | |
1518 | wasn't compiled in to the daemon (avoiding a warning in the logs). | |
1519 | ||
1520 | - Fixed the inclusion of per-dir merge files from implied dirs. | |
1521 | ||
1522 | - Fixed the support/rrsync script to work with the latest options that rsync | |
1523 | sends (including its flag-specifying use of `-e` to the server). | |
1524 | ||
1525 | ### ENHANCEMENTS: | |
1526 | ||
1527 | - Added the `--old-dirs` (`--old-d`) option to make it easier for a user to | |
1528 | ask for file-listings with older rsync versions (this is easier than having | |
1529 | to type `-r --exclude='/*/*'` manually). | |
1530 | ||
1531 | - When getting an error while asking an older rsync daemon for a file listing, | |
1532 | rsync will try to notice if the error is a rejection of the `--dirs` (`-d`) | |
1533 | option and let the user know how to work around the issue. | |
1534 | ||
1535 | - Added a few more `--no-OPTION` overrides. | |
1536 | ||
1537 | - Improved the documentation of the `--append` option. | |
1538 | ||
1539 | - Improved the documentation of the filter/exclude/include daemon parameters. | |
1540 | ||
1541 | ### INTERNAL: | |
1542 | ||
1543 | - Fixed a couple minor bugs in the included popt library (ones which I sent to | |
1544 | the official popt project for inclusion in the 1.14 release). | |
1545 | ||
1546 | - Fixed a stat() call that should have been `do_stat()` so that the proper | |
1547 | normal/64-bit stat() function gets called. (Was in an area that should not | |
1548 | have caused problems, though.) | |
1549 | ||
1550 | - Changed the file-glob code to do a directory scan without using the `glob` | |
1551 | and `glob.h`. This lets us do the globbing with less memory churn, and also | |
1552 | avoid adding daemon-excluded items to the returned args. | |
1553 | ||
1554 | ### DEVELOPER RELATED: | |
1555 | ||
1556 | - The configure script tries to get the user's compiler to not warn about | |
1557 | unused function parameters if the build is not including one or more of the | |
1558 | ACL/xattrs/iconv features. | |
1559 | ||
1560 | - The configure script now has better checks for figuring out if the included | |
1561 | popt code should be used or not. | |
1562 | ||
1563 | - Fixed two testsuite glitches: avoid a failure if someone's `cd` command | |
1564 | outputs the current directory when cd-ing to a relative path, and made the | |
1565 | itemized test query how rsync was built to determine if it should expect | |
1566 | hard-linked symlinks or not. | |
1567 | ||
1568 | - Updated the testsuite to verify that various bug fixes remain fixed. | |
1569 | ||
1570 | - The RPM spec file was updated to have: (1) comments for how to use the | |
1571 | rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file. | |
1572 | ||
1573 | - Updated the build scripts to work with a revised FTP directory structure. | |

1578 | # NEWS for rsync 3.0.0 (1 Mar 2008) | |
1579 | ||
1580 | Protocol: 30 (changed) | |
1581 | ||
1582 | ## Changes since 2.6.9: | |
1583 | ||
1584 | ### NOTABLE CHANGES IN BEHAVIOR: | |
1585 | ||
1586 | - The handling of implied directories when using `--relative` has changed to | |
1587 | send them as directories (e.g. no implied dir is ever sent as a symlink). | |
1588 | This avoids unexpected behavior and should not adversely affect most people. | |
1589 | If you're one of those rare individuals who relied upon having an implied | |
1590 | dir be duplicated as a symlink, you should specify the transfer of the | |
1591 | symlink and the transfer of the referent directory as separate args. (See | |
1592 | also `--keep-dirlinks` and `--no-implied-dirs`.) Also, exclude rules no | |
1593 | longer have a partial effect on implied dirs. | |
1594 | ||
1595 | - Requesting a remote file-listing without specifying `-r` (`--recursive`) now | |
1596 | sends the `-d` (`--dirs`) option to the remote rsync rather than sending | |
1597 | `-r` along with an extra exclude of `/*/*`. If the remote rsync does not | |
1598 | understand the `-d` option (i.e. it is 2.6.3 or older), you will need to | |
1599 | either turn off `-d` (`--no-d`), or specify `-r --exclude='/*/*'` manually. | |
1600 | ||
1601 | - In `--dry-run` mode, the last line of the verbose summary text is output | |
1602 | with a "(DRY RUN)" suffix to help remind you that no updates were made. | |
1603 | Similarly, `--only-write-batch` outputs `(BATCH ONLY)`. | |
1604 | ||
1605 | - A writable rsync daemon with `use chroot` disabled now defaults to a | |
1606 | symlink-munging behavior designed to make symlinks safer while also allowing | |
1607 | absolute symlinks to be stored and retrieved. This also has the effect of | |
1608 | making symlinks unusable while they're in the daemon's hierarchy. See the | |
1609 | daemon's `munge symlinks` parameter for details. | |
1610 | ||
1611 | - Starting up an extra copy of an rsync daemon will not clobber the pidfile | |
1612 | for the running daemon -- if the pidfile exists, the new daemon will exit | |
1613 | with an error. This means that your wrapper script that starts the rsync | |
1614 | daemon should be made to handle lock-breaking (if you want any automatic | |
1615 | breaking of locks to be done). | |
1616 | ||
1617 | ### BUG FIXES: | |
1618 | ||
1619 | - A daemon with `use chroot = no` and excluded items listed in the daemon | |
1620 | config file now properly checks an absolute-path arg specified for these | |
1621 | options: `--compare-dest`, `--link-dest`, `--copy-dest`, `--partial-dir`, | |
1622 | `--backup-dir`, `--temp-dir`, and `--files-from`. | |
1623 | ||
1624 | - A daemon can now be told to disable all user- and group-name translation on | |
1625 | a per-module basis. This avoids a potential problem with a writable daemon | |
1626 | module that has `use chroot` enabled -- if precautions weren't taken, a user | |
1627 | could try to add a missing library and get rsync to use it. This makes rsync | |
1628 | safer by default, and more configurable when id- translation is not desired. | |
1629 | See the daemon's `numeric ids` parameter for full details. | |
1630 | ||
1631 | - A chroot daemon can now indicate which part of its path should affect the | |
1632 | chroot call, and which part should become an inside-chroot path for the | |
1633 | module. This allows you to have outside-the-transfer paths (such as for | |
1634 | libraries) even when you enable chroot protection. The idiom used in the | |
1635 | rsyncd.conf file is: `path = /chroot/dirs/./dirs/inside` | |
1636 | ||
1637 | - If a file's data arrived successfully on the receiving side but the rename | |
1638 | of the temporary file to the destination file failed AND the | |
1639 | `--remove-source-files` (or the deprecated `--remove-sent-files`) option was | |
1640 | specified, rsync no longer erroneously removes the associated source file. | |
1641 | ||
1642 | - Fixed the output of `-ii` when combined with one of the `--*-dest` options: | |
1643 | it now itemizes all the items, not just the changed ones. | |
1644 | ||
1645 | - Made the output of all file types consistent when using a `--*-dest` option. | |
1646 | Prior versions would output too many creation events for matching items. | |
1647 | ||
1648 | - The code that waits for a child pid now handles being interrupted by a | |
1649 | signal. This fixes a problem with the pre-xfer exec function not being able | |
1650 | to get the exit status from the script. | |
1651 | ||
1652 | - A negated filter rule (i.e. with a '!' modifier) no longer loses the | |
1653 | negation when sending the filter rules to the remote rsync. | |
1654 | ||
1655 | - Fixed a problem with the `--out-format` (aka `--log-format`) option %f: it | |
1656 | no longer outputs superfluous directory info for a non-daemon rsync. | |
1657 | ||
1658 | - Fixed a problem with `-vv` (double `--verbose`) and `--stats` when `pushing` | |
1659 | files (which includes local copies). Version 2.6.9 would complete the copy, | |
1660 | but exit with an error when the receiver output its memory stats. | |
1661 | ||
1662 | - If `--password-file` is used on a non-daemon transfer, rsync now complains | |
1663 | and exits. This should help users figure out that they can't use this option | |
1664 | to control a remote shell's password prompt. | |
1665 | ||
1666 | - Make sure that directory permissions of a newly-created destination | |
1667 | directory are handled right when `--perms` is left off. | |
1668 | ||
1669 | - The itemized output of a newly-created destination directory is now output | |
1670 | as a creation event, not a change event. | |
1671 | ||
1672 | - Improved `--hard-link` so that more corner cases are handled correctly when | |
1673 | combined with options such as `--link-dest` and/or `--ignore-existing`. | |
1674 | ||
1675 | - The `--append` option no longer updates a file that has the same size. | |
1676 | ||
1677 | - Fixed a bug when combining `--backup` and `--backup-dir` with `--inplace`: | |
1678 | any missing backup directories are now created. | |
1679 | ||
1680 | - Fixed a bug when using `--backup` and `--inplace` with `--whole-file` or | |
1681 | `--read-batch`: backup files are actually created now. | |
1682 | ||
1683 | - The daemon pidfile is checked and created sooner in the startup sequence. | |
1684 | ||
1685 | - If a daemon module's `path` value is not an absolute pathname, the code now | |
1686 | makes it absolute internally (making it work properly). | |
1687 | ||
1688 | - Ensure that a temporary file always has owner-write permission while we are | |
1689 | writing to it. This avoids problems with some network filesystems when | |
1690 | transferring read-only files. | |
1691 | ||
1692 | - Any errors output about password-file reading no longer cause an error at | |
1693 | the end of the run about a partial transfer. | |
1694 | ||
1695 | - The `--read-batch` option for protocol 30 now ensures that several more | |
1696 | options are set correctly for the current batch file: `--iconv`, `--acls`, | |
1697 | `--xattrs`, `--inplace`, `--append`, and `--append-verify`. | |
1698 | ||
1699 | - Using `--only-write-batch` to a daemon receiver now works properly (older | |
1700 | versions would update some files while writing the batch). | |
1701 | ||
1702 | - Avoid outputting a "file has vanished" message when the file is a broken | |
1703 | symlink and `--copy-unsafe-links` or `--copy-dirlinks` is used (the code | |
1704 | already handled this for `--copy-links`). | |
1705 | ||
1706 | - Fixed the combination of `--only-write-batch` and `--dry-run`. | |
1707 | ||
1708 | - Fixed rsync's ability to remove files that are not writable by the file's | |
1709 | owner when rsync is running as the same user. | |
1710 | ||
1711 | - When transferring large files, the sender's hashtable of checksums is kept | |
1712 | at a more reasonable state of fullness (no more than 80% full) so that the | |
1713 | scanning of the hashtable will not bog down as the number of blocks | |
1714 | increases. | |
1715 | ||
1716 | ### ENHANCEMENTS: | |
1717 | ||
1718 | - A new incremental-recursion algorithm is now used when rsync is talking to | |
1719 | another 3.x version. This starts the transfer going more quickly (before all | |
1720 | the files have been found), and requires much less memory. See the | |
1721 | `--recursive` option in the manpage for some restrictions. | |
1722 | ||
1723 | - Lowered memory use in the non-incremental-recursion algorithm for typical | |
1724 | option values (usually saving from 21-29 bytes per file). | |
1725 | ||
1726 | - The default `--delete` algorithm is now `--delete-during` when talking to a | |
1727 | 3.x rsync. This is a faster scan than using `--delete-before` (which is the | |
1728 | default when talking to older rsync versions), and is compatible with the | |
1729 | new incremental recursion mode. | |
1730 | ||
1731 | - Rsync now allows multiple remote-source args to be specified rather than | |
1732 | having to rely on a special space-splitting side-effect of the remote- | |
1733 | shell. Additional remote args must specify the same host or an empty one | |
1734 | (e.g. empty: `:file1` or `::module/file2`). For example, this means that | |
1735 | local use of brace expansion now works: `rsync -av host:dir/{f1,f2} .` | |
1736 | ||
1737 | - Added the `--protect-args` (`-s`) option, that tells rsync to send most of | |
1738 | the command-line args at the start of the transfer rather than as args to | |
1739 | the remote-shell command. This protects them from space-splitting, and only | |
1740 | interprets basic wildcard special shell characters (`*?[`). | |
1741 | ||
1742 | - Added the `--delete-delay` option, which is a more efficient way to delete | |
1743 | files at the end of the transfer without needing a separate delete pass. | |
1744 | ||
1745 | - Added the `--acls` (`-A`) option to preserve Access Control Lists. This is | |
1746 | an improved version of the prior patch that was available, and it even | |
1747 | supports OS X ACLs. If you need to have backward compatibility with old, | |
1748 | ACL-patched versions of rsync, apply the acls.diff file from the patches | |
1749 | dir. | |
1750 | ||
1751 | - Added the `--xattrs` (`-X`) option to preserve extended attributes. This is | |
1752 | an improved version of the prior patch that was available, and it even | |
1753 | supports OS X xattrs (which includes their resource fork data). If you need | |
1754 | to have backward compatibility with old, xattr-patched versions of rsync, | |
1755 | apply the xattrs.diff file from the patches dir. | |
1756 | ||
1757 | - Added the `--fake-super` option that allows a non-super user to preserve all | |
1758 | attributes of a file by using a special extended-attribute idiom. It even | |
1759 | supports the storing of foreign ACL data on your backup server. There is | |
1760 | also an analogous `fake super` parameter for an rsync daemon. | |
1761 | ||
1762 | - Added the `--iconv` option, which allows rsync to convert filenames from one | |
1763 | character-set to another during the transfer. The default is to make this | |
1764 | feature available as long as your system has `iconv_open()`. If compilation | |
1765 | fails, specify `--disable-iconv` to configure, and then rebuild. If you want | |
1766 | rsync to perform character-set conversions by default, you can specify | |
1767 | `--enable-iconv=CONVERT_STRING` with the default value for the `--iconv` | |
1768 | option that you wish to use. For example, `--enable-iconv=.` is a good | |
1769 | choice. See the rsync manpage for an explanation of the `--iconv` option's | |
1770 | settings. | |
1771 | ||
1772 | - A new daemon config parameter, `charset`, lets you control the character- | |
1773 | set that is used during an `--iconv` transfer to/from a daemon module. You | |
1774 | can also set your daemon to refuse `no-iconv` if you want to force the | |
1775 | client to use an `--iconv` transfer (requiring an rsync 3.x client). | |
1776 | ||
1777 | - Added the `--skip-compress=LIST` option to override the default list of file | |
1778 | suffixes that will not be compressed when using `--compress` (`-z`). | |
1779 | ||
1780 | - The daemon's default for `dont compress` was extended to include: `*.7z` | |
1781 | `*.mp[34]` `*.mov` `*.avi` `*.ogg` `*.jpg` `*.jpeg` and the name-matching routine was also | |
1782 | optimized to run more quickly. | |
1783 | ||
1784 | - The `--max-delete` option now outputs a warning if it skipped any file | |
1785 | deletions, including a count of how many deletions were skipped. (Older | |
1786 | versions just silently stopped deleting things.) | |
1787 | ||
1788 | - You may specify `--max-delete=0` to a 3.0.0 client to request that it warn | |
1789 | about extraneous files without deleting anything. If you're not sure what | |
1790 | version the client is, you can use the less-obvious `--max-delete=-1`, as | |
1791 | both old and new versions will treat that as the same request (though older | |
1792 | versions don't warn). | |
1793 | ||
1794 | - The `--hard-link` option now uses less memory on both the sending and | |
1795 | receiving side for all protocol versions. For protocol 30, the use of a | |
1796 | hashtable on the sending side allows us to more efficiently convey to the | |
1797 | receiver what files are linked together. This reduces the amount of data | |
1798 | sent over the socket by a considerable margin (rather than adding more | |
1799 | data), and limits the in-memory storage of the device+inode information to | |
1800 | just the sending side for the new protocol 30, or to the receiving side when | |
1801 | speaking an older protocol (note that older rsync versions kept the | |
1802 | device+inode information on both sides). | |
1803 | ||
1804 | - The filter rules now support a perishable (`p`) modifier that marks rules | |
1805 | that should not have an effect in a directory that is being deleted. e.g. | |
1806 | `-f '-p .svn/'` would only affect `live` .svn directories. | |
1807 | ||
1808 | - Rsync checks all the alternate-destination args for validity (e.g. | |
1809 | `--link-dest`). This lets the user know when they specified a directory that | |
1810 | does not exist. | |
1811 | ||
1812 | - If we get an ENOSYS error setting the time on a symlink, we don't complain | |
1813 | about it anymore (for those systems that even support the setting of the | |
1814 | modify-time on a symlink). | |
1815 | ||
1816 | - Protocol 30 now uses MD5 checksums instead of MD4. | |
1817 | ||
1818 | - Changed the `--append` option to not checksum the existing data in the | |
1819 | destination file, which speeds up file appending. | |
1820 | ||
1821 | - Added the `--append-verify` option, which works like the older `--append` | |
1822 | option (verifying the existing data in the destination file). For | |
1823 | compatibility with older rsync versions, any use of `--append` that is | |
1824 | talking protocol 29 or older will revert to the `--append-verify` method. | |
1825 | ||
1826 | - Added the `--contimeout=SECONDS` option that lets the user specify a | |
1827 | connection timeout for rsync daemon access. | |
1828 | ||
1829 | - Documented and extended the support for the `RSYNC_CONNECT_PROG` variable | |
1830 | that can be used to enhance the client side of a daemon connection. | |
1831 | ||
1832 | - Improved the dashes and double-quotes in the nroff manpage output. | |
1833 | ||
1834 | - Rsync now supports a lot more `--no-OPTION` override options. | |
1835 | ||
1836 | ### INTERNAL: | |
1837 | ||
1838 | - The file-list sorting algorithm now uses a sort that keeps any same- named | |
1839 | items in the same order as they were specified. This allows rsync to always | |
1840 | ensure that the first of the duplicates is the one that will be included in | |
1841 | the copy. The new sort is also faster than the glibc version of qsort() and | |
1842 | mergesort(). | |
1843 | ||
1844 | - Rsync now supports the transfer of 64-bit timestamps (`time_t` values). | |
1845 | ||
1846 | - Made the file-deletion code use a little less stack when recursing through a | |
1847 | directory hierarchy of extraneous files. | |
1848 | ||
1849 | - Fixed a build problem with older (2.x) versions of gcc. | |
1850 | ||
1851 | - Added some isType() functions that make dealing with signed characters | |
1852 | easier without forcing variables via casts. | |
1853 | ||
1854 | - Changed strcat/strcpy/sprintf function calls to use safer versions. | |
1855 | ||
1856 | - Upgraded the included popt version to 1.10.2 and improved its use of | |
1857 | string-handling functions. | |
1858 | ||
1859 | - Added missing prototypes for compatibility functions from the lib dir. | |
1860 | ||
1861 | - Configure determines if iconv() has a const arg, allowing us to avoid a | |
1862 | compiler warning. | |
1863 | ||
1864 | - Made the sending of some numbers more efficient for protocol 30. | |
1865 | ||
1866 | - Make sure that a daemon process doesn't mind if the client was weird and | |
1867 | omitted the `--server` option. | |
1868 | ||
1869 | - There are more internal logging categories available in protocol 30 than the | |
1870 | age-old FINFO and FERROR, including `FERROR_XFER` and FWARN. These new | |
1871 | categories allow some errors and warnings to go to stderr without causing an | |
1872 | erroneous end-of-run warning about some files not being able to be | |
1873 | transferred. | |
1874 | ||
1875 | - Improved the use of `const` on pointers. | |
1876 | ||
1877 | - Improved J.W.'s `pool_alloc` routines to add a way of incrementally freeing | |
1878 | older sections of a pool's memory. | |
1879 | ||
1880 | - The getaddrinfo.c compatibility code in the `lib` dir was replaced with some | |
1881 | new code (derived from samba, derived from PostgreSQL) that has a better | |
1882 | license than the old code. | |
1883 | ||
1884 | ### DEVELOPER RELATED: | |
1885 | ||
1886 | - Rsync is now licensed under the GPLv3 or later. | |
1887 | ||
1888 | - Rsync is now being maintained in a `git` repository instead of CVS (though | |
1889 | the old CVS repository still exists for historical access). Several | |
1890 | maintenance scripts were updated to work with git. | |
1891 | ||
1892 | - Generated files are no longer committed into the source repository. The | |
1893 | autoconf and autoheader commands are now automatically run during the normal | |
1894 | use of `configure` and `make`. The latest dev versions of all generated | |
1895 | files can also be copied from the samba.org web site (see the prepare-source | |
1896 | script's fetch option). | |
1897 | ||
1898 | - The `patches` directory of diff files is now built from branches in the | |
1899 | rsync git repository (branch patch/FOO creates file patches/FOO.diff). This | |
1900 | directory is now distributed in a separate separate tar file named | |
1901 | rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz. | |
1902 | ||
1903 | - The proto.h file is now built using a simple perl script rather than a | |
1904 | complex awk script, which proved to be more widely compatible. | |
1905 | ||
1906 | - When running the tests, we now put our per-test temp dirs into a sub- | |
1907 | directory named testtmp (which is created, if missing). This allows someone | |
1908 | to symlink the testtmp directory to another filesystem (which is useful if | |
1909 | the build dir's filesystem does not support ACLs and xattrs, but another | |
1910 | filesystem does). | |
1911 | ||
1912 | - Rsync now has a way of handling protocol-version changes during the | |
1913 | development of a new protocol version. This causes any out-of-sync versions | |
1914 | to speak an older protocol rather than fail in a cryptic manner. This | |
1915 | addition makes it safer to deploy a pre-release version that may interact | |
1916 | with the public. This new exchange of sub-version info does not interfere | |
1917 | with the `{MIN,MAX}_PROTOCOL_VERSION` checking algorithm (which does not | |
1918 | have enough range to allow the main protocol number to be incremented for | |
1919 | every minor tweak in that happens during development). | |
1920 | ||
1921 | - The csprotocol.txt file was updated to mention the daemon protocol change in | |
1922 | the 3.0.0 release. | |

1927 | # NEWS for rsync 2.6.9 (6 Nov 2006) | |
1928 | ||
1929 | Protocol: 29 (unchanged) | |
1930 | ||
1931 | ## Changes since 2.6.8: | |
1932 | ||
1933 | ### BUG FIXES: | |
1934 | ||
1935 | - If rsync is interrupted via a handled signal (such as SIGINT), it will once | |
1936 | again clean-up its temp file from the destination dir. | |
1937 | ||
1938 | - Fixed an overzealous sanitizing bug in the handling of the `--link-dest`, | |
1939 | `--copy-dest`, and `--compare-dest` options to a daemon without chroot: if | |
1940 | the copy's destination dir is deeper than the top of the module's path, | |
1941 | these options now accept a safe number of parent-dir (../) references (since | |
1942 | these options are relative to the destination dir). The old code incorrectly | |
1943 | chopped off all `../` prefixes for these options, no matter how deep the | |
1944 | destination directory was in the module's hierarchy. | |
1945 | ||
1946 | - Fixed a bug where a deferred info/error/log message could get sent directly | |
1947 | to the sender instead of being handled by rwrite() in the generator. This | |
1948 | fixes an `unexpected tag 3` fatal error, and should also fix a potential | |
1949 | problem where a deferred info/error message from the receiver might bypass | |
1950 | the log file and get sent only to the client process. (These problems could | |
1951 | only affect an rsync daemon that was receiving files.) | |
1952 | ||
1953 | - Fixed a bug when `--inplace` was combined with a `--*-dest` option and we | |
1954 | update a file's data using an alternate basis file. The code now notices | |
1955 | that it needs to copy the matching data from the basis file instead of | |
1956 | (wrongly) assuming that it was already present in the file. | |
1957 | ||
1958 | - Fixed a bug where using `--dry-run` with a `--*-dest` option with a path | |
1959 | relative to a directory that does not yet exist: the affected option gets | |
1960 | its proper path value so that the output of the dry-run is right. | |
1961 | ||
1962 | - Fixed a bug in the %f logfile escape when receiving files: the destination | |
1963 | path is now included in the output (e.g. you can now tell when a user | |
1964 | specifies a subdir inside a module). | |
1965 | ||
1966 | - If the receiving side fails to create a directory, it will now skip trying | |
1967 | to update everything that is inside that directory. | |
1968 | ||
1969 | - If `--link-dest` is specified with `--checksum` but without `--times`, rsync | |
1970 | will now allow a hard-link to be created to a matching link-dest file even | |
1971 | when the file's modify-time doesn't match the server's file. | |
1972 | ||
1973 | - The daemon now calls more timezone-using functions prior to doing a chroot. | |
1974 | This should help some C libraries to generate proper timestamps from inside | |
1975 | a chrooted daemon (and to not try to access /etc/timezone over and over | |
1976 | again). | |
1977 | ||
1978 | - Fixed a bug in the handling of an absolute `--partial-dir=ABS_PATH` option: | |
1979 | it now deletes an alternate basis file from the partial-dir that was used to | |
1980 | successfully update a destination file. | |
1981 | ||
1982 | - Fixed a bug in the handling of `--delete-excluded` when using a per-dir | |
1983 | merge file: the merge file is now honored on the receiving side, and only | |
1984 | its unqualified include/exclude commands are ignored (just as is done for | |
1985 | global include/excludes). | |
1986 | ||
1987 | - Fixed a recent bug where `--delete` was not working when transferring from | |
1988 | the root (/) of the filesystem with `--relative` enabled. | |
1989 | ||
1990 | - Fixed a recent bug where an `--exclude='*'` could affect the root (/) of the | |
1991 | filesystem with `--relative` enabled. | |
1992 | ||
1993 | - When `--inplace` creates a file, it is now created with owner read/write | |
1994 | permissions (0600) instead of no permissions at all. This avoids a problem | |
1995 | continuing a transfer that was interrupted (since `--inplace` will not | |
1996 | update a file that has no write permissions). | |
1997 | ||
1998 | - If either `--remove-source-files` or `--remove-sent-files` is enabled and we | |
1999 | are unable to remove the source file, rsync now outputs an error. | |
2000 | ||
2001 | - Fixed a bug in the daemon's `incoming chmod` rule: newly-created directories | |
2002 | no longer get the 'F' (file) rules applied to them. | |
2003 | ||
2004 | - Fixed an infinite loop bug when a filter rule was rejected due to being | |
2005 | overly long. | |
2006 | ||
2007 | - When the server receives a `--partial-dir` option from the client, it no | |
2008 | longer runs the client-side code that adds an assumed filter rule (since the | |
2009 | client will be sending us the rules in the usual manner, and they may have | |
2010 | chosen to override the auto-added rule). | |
2011 | ||
2012 | ### ENHANCEMENTS: | |
2013 | ||
2014 | - Added the `--log-file=FILE` and `--log-file-format=FORMAT` options. These | |
2015 | can be used to tell any rsync to output what it is doing to a log file. | |
2016 | They work with a client rsync, a non-daemon server rsync (see the man page | |
2017 | for instructions), and also allows the overriding of rsyncd.conf settings | |
2018 | when starting a daemon. | |
2019 | ||
2020 | - The `--log-format` option was renamed to be `--out-format` to avoid | |
2021 | confusing it with affecting the log-file output. (The old option remains as | |
2022 | an alias for the new to preserve backward compatibility.) | |
2023 | ||
2024 | - Made `log file` and `syslog facility` settable on a per-module basis in the | |
2025 | daemon's config file. | |
2026 | ||
2027 | - Added the `--remove-source-files` option as a replacement for the (now | |
2028 | deprecated) `--remove-sent-files` option. This new option removes all | |
2029 | non-dirs from the source directories, even if the file was already | |
2030 | up-to-date. This fixes a problem where interrupting an rsync that was using | |
2031 | `--remove-sent-files` and restarting it could leave behind a file that the | |
2032 | earlier rsync synchronized, but didn't get to remove. (The deprecated | |
2033 | `--remove-sent-files` is still understood for now, and still behaves in the | |
2034 | same way as before.) | |
2035 | ||
2036 | - Added the option `--no-motd` to suppress the message-of-the-day output from | |
2037 | a daemon when doing a copy. (See the manpage for a caveat.) | |
2038 | ||
2039 | - Added a new environment variable to the pre-/post-xfer exec commands (in the | |
2040 | daemon's config file): `RSYNC_PID`. This value will be the same in both the | |
2041 | pre- and post-xfer commands, so it can be used as a unique ID if the | |
2042 | pre-xfer command wants to cache some arg/request info for the post-xfer | |
2043 | command. | |
2044 | ||
2045 | ### INTERNAL: | |
2046 | ||
2047 | - Did a code audit using IBM's code-checker program and made several changes, | |
2048 | including: replacing most of the strcpy() and sprintf() calls with | |
2049 | strlcpy(), snprintf(), and memcpy(), adding a 0-value to an enum that had | |
2050 | been intermingling a literal 0 with the defined enum values, silencing some | |
2051 | uninitialized memory checks, marking some functions with a `noreturn` | |
2052 | attribute, and changing an `if` that could never succeed on some platforms | |
2053 | into a pre-processor directive that conditionally compiles the code. | |
2054 | ||
2055 | - Fixed a potential bug in `f_name_cmp()` when both the args are a top-level | |
2056 | `.` dir (which doesn't happen in normal operations). | |
2057 | ||
2058 | - Changed `exit_cleanup()` so that it can never return instead of exit. The | |
2059 | old code might return if it found the `exit_cleanup()` function was being | |
2060 | called recursively. The new code is segmented so that any recursive calls | |
2061 | move on to the next step of the exit-processing. | |
2062 | ||
2063 | - The macro WIFEXITED(stat) will now be defined if the OS didn't already | |
2064 | define it. | |
2065 | ||
2066 | ### DEVELOPER RELATED: | |
2067 | ||
2068 | - The acls.diff and xattrs.diff patches have received a bunch of work to make | |
2069 | them much closer to being acceptable in the main distribution. The xattrs | |
2070 | patch also has some preliminary Mac OS X and FreeBSD compatibility code that | |
2071 | various system types to exchange extended file-attributes. | |
2072 | ||
2073 | - A new diff in the patches dir, fake-root.diff, allows rsync to maintain a | |
2074 | backup hierarchy with full owner, group, and device info without actually | |
2075 | running as root. It does this using a special extended attribute, so it | |
2076 | depends on xattrs.diff (which depends on acls.diff). | |
2077 | ||
2078 | - The rsync.yo and rsyncd.conf.yo files have been updated to work better with | |
2079 | the latest yodl 2.x releases. | |
2080 | ||
2081 | - Updated config.guess and config.sub to their 2006-07-02 versions. | |
2082 | ||
2083 | - Updated various files to include the latest FSF address and to have | |
2084 | consistent opening comments. | |

2089 | # NEWS for rsync 2.6.8 (22 Apr 2006) | |
2090 | ||
2091 | Protocol: 29 (unchanged) | |
2092 | ||
2093 | ## Changes since 2.6.7: | |
2094 | ||
2095 | ### BUG FIXES: | |
2096 | ||
2097 | - Fixed a bug in the exclude code where an anchored exclude without any | |
2098 | wildcards fails to match an absolute source arg, but only when `--relative` | |
2099 | is in effect. | |
2100 | ||
2101 | - Improved the I/O code for the generator to fix a potential hang when the | |
2102 | receiver gets an EOF on the socket but the generator's select() call never | |
2103 | indicates that the socket is writable for it to be notified about the EOF. | |
2104 | (This can happen when using stunnel). | |
2105 | ||
2106 | - Fixed a problem with the file-reading code where a failed read (such as that | |
2107 | caused by a bad sector) would not advance the file's read-position beyond | |
2108 | the failed read's data. | |
2109 | ||
2110 | - Fixed a logging bug where the `log file` directive was not being honored in | |
2111 | a single-use daemon (one spawned by a remote-shell connection or by init). | |
2112 | ||
2113 | - If rsync cannot honor the `--delete` option, we output an error and exit | |
2114 | instead of silently ignoring the option. | |
2115 | ||
2116 | - Fixed a bug in the `--link-dest` code that prevented special files (such as | |
2117 | fifos) from being linked. | |
2118 | ||
2119 | - The ability to hard-link symlinks and special files is now determined at | |
2120 | configure time instead of at runtime. This fixes a bug with `--link-dest` | |
2121 | creating a hard-link to a symlink's referent on a BSD system. | |
2122 | ||
2123 | ### ENHANCEMENTS: | |
2124 | ||
2125 | - In daemon mode, if rsync fails to bind to the requested port, the error(s) | |
2126 | returned by socket() and/or bind() are now logged. | |
2127 | ||
2128 | - When we output a fatal error, we now output the version of rsync in the | |
2129 | message. | |
2130 | ||
2131 | - Improved the documentation for the `--owner` and `--group` options. | |
2132 | ||
2133 | - The rsyncstats script in `support` has an improved line-parsing regex that | |
2134 | is easier to read and also makes it to parse syslog-generated lines. | |
2135 | ||
2136 | - A new script in `support`: file-attr-restore, can be used to restore the | |
2137 | attributes of a file-set (the permissions, ownership, and group info) taken | |
2138 | from the cached output of a `find ARG... -ls` command. | |
2139 | ||
2140 | ### DEVELOPER RELATED: | |
2141 | ||
2142 | - Removed the unused function `write_int_named()`, the unused variable | |
2143 | `io_read_phase`, and the rarely used variable `io_write_phase`. This also | |
2144 | elides the confusing 'phase "unknown"' part of one error message. | |
2145 | ||
2146 | - Removed two unused configure checks and two related (also unused) | |
2147 | compatibility functions. | |
2148 | ||
2149 | - The xattrs.diff patch received a security fix that prevents a potential | |
2150 | buffer overflow in the `receive_xattr()` code. | |
2151 | ||
2152 | - The acls.diff patch has been improved quite a bit, with more to come. | |
2153 | ||
2154 | - A new patch was added: log-file.diff. This contains an early version of a | |
2155 | future option, `--log-file=FILE`, that will allow any rsync to log its | |
2156 | actions to a file (something that only a daemon supports at present). | |
2157 | ||

2160 | ||
2161 | # NEWS for rsync 2.6.7 (11 Mar 2006) | |
2162 | ||
2163 | Protocol: 29 (unchanged) | |
2164 | ||
2165 | ## Changes since 2.6.6: | |
2166 | ||
2167 | ### OUTPUT CHANGES: | |
2168 | ||
2169 | - The letter 'D' in the itemized output was being used for both devices | |
2170 | (character or block) as well as other special files (such as fifos and named | |
2171 | sockets). This has changed to separate non-device special files under the | |
2172 | 'S' designation (e.g. `cS+++++++ path/fifo`). See also the `--specials` | |
2173 | option, below. | |
2174 | ||
2175 | - The way rsync escapes unreadable characters has changed. First, rsync now | |
2176 | has support for recognizing valid multibyte character sequences in your | |
2177 | current locale, allowing it to escape fewer characters than before for a | |
2178 | locale such as UTF-8. Second, it now uses an escape idiom of `\#123`, which | |
2179 | is the literal string `\#` followed by exactly 3 octal digits. Rsync no | |
2180 | longer doubles a backslash character in a filename (e.g. it used to output | |
2181 | `foo\\bar` when copying `foo\bar`) -- now it only escapes a backslash that | |
2182 | is followed by a hash-sign and 3 digits (0-9) (e.g. it will output | |
2183 | `foo\#134#789` when copying `foo\#789`). See also the `--8-bit-output` | |
2184 | (`-8`) option, mentioned below. | |
2185 | ||
2186 | Script writers: the local rsync is the one that outputs escaped names, so if | |
2187 | you need to support unescaping of filenames for older rsyncs, I'd suggest | |
2188 | that you parse the output of `rsync --version` and only use the old | |
2189 | unescaping rules for 2.6.5 and 2.6.6. | |
2190 | ||
2191 | ### BUG FIXES: | |
2192 | ||
2193 | - Fixed a really old bug that caused `--checksum` (`-c`) to checksum all the | |
2194 | files encountered during the delete scan (ouch). | |
2195 | ||
2196 | - Fixed a potential hang in a remote generator: when the receiver gets a | |
2197 | read-error on the socket, it now signals the generator about this so that | |
2198 | the generator does not try to send any of the terminating error messages to | |
2199 | the client (avoiding a potential hang in some setups). | |
2200 | ||
2201 | - Made hard-links work with symlinks and devices again. | |
2202 | ||
2203 | - If the sender gets an early EOF reading a source file, we propagate this | |
2204 | error to the receiver so that it can discard the file and try requesting it | |
2205 | again (which is the existing behavior for other kinds of read errors). | |
2206 | ||
2207 | - If a device-file/special-file changes permissions, rsync now updates the | |
2208 | permissions without recreating the file. | |
2209 | ||
2210 | - If the user specifies a remote-host for both the source and destination, we | |
2211 | now output a syntax error rather than trying to open the destination | |
2212 | hostspec as a filename. | |
2213 | ||
2214 | - When `--inplace` creates a new destination file, rsync now creates it with | |
2215 | permissions 0600 instead of 0000 -- this makes restarting possible when the | |
2216 | transfer gets interrupted in the middle of sending a new file. | |
2217 | ||
2218 | - Reject the combination of `--inplace` and `--sparse` since the sparse-output | |
2219 | algorithm doesn't work when overwriting existing data. | |
2220 | ||
2221 | - Fixed the directory name in the error that is output when `pop_dir()` fails. | |
2222 | ||
2223 | - Really fixed the parsing of a `!` entry in .cvsignore files this time. | |
2224 | ||
2225 | - If the generator gets a stat() error on a file, output it (this used to | |
2226 | require at least `-vv` for the error to be seen). | |
2227 | ||
2228 | - If waitpid() fails or the child rsync didn't exit cleanly, we now handle the | |
2229 | exit status properly and generate a better error. | |
2230 | ||
2231 | - Fixed some glitches in the double-verbose output when using `--copy-dest`, | |
2232 | `--link-dest`, or `--compare-dest`. Also improved how the verbose output | |
2233 | handles hard-links (within the transfer) that had an up-to-date alternate | |
2234 | `dest` file, and copied files (via `--copy-dest`). | |
2235 | ||
2236 | - Fixed the matching of the dont-compress items (e.g. `*.gz`) against files | |
2237 | that have a path component containing a slash. | |
2238 | ||
2239 | - If the code reading a filter/exclude file gets an EINTR error, rsync now | |
2240 | clears the error flag on the file handle so it can keep on reading. | |
2241 | ||
2242 | - If `--relative` is active, the sending side cleans up trailing `/` or `/.` | |
2243 | suffixes to avoid triggering a bug in older rsync versions. Also, we now | |
2244 | reject a `..` dir if it would be sent as a relative dir. | |
2245 | ||
2246 | - If a non-directory is in the way of a directory and rsync is run with | |
2247 | `--dry-run` and `--delete`, rsync no longer complains about not being able | |
2248 | to opendir() the not-yet present directory. | |
2249 | ||
2250 | - When `--list-only` is used and a non-existent local destination dir was also | |
2251 | specified as a destination, rsync no longer generates a warning about being | |
2252 | unable to create the missing directory. | |
2253 | ||
2254 | - Fixed some problems with `--relative --no-implied-dirs` when the destination | |
2255 | directory did not yet exist: we can now create a symlink or device when it | |
2256 | is the first thing in the missing dir, and `--fuzzy` no longer complains | |
2257 | about being unable to open the missing dir. | |
2258 | ||
2259 | - Fixed a bug where the `--copy-links` option would not affect implied | |
2260 | directories without `--copy-unsafe-links` (see `--relative`). | |
2261 | ||
2262 | - Got rid of the need for `--force` to be used in some circumstances with | |
2263 | `--delete-after` (making it consistent with | |
2264 | `--delete-before`/`--delete-during`). | |
2265 | ||
2266 | - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this when a | |
2267 | file is too large (rsync handles the write error). | |
2268 | ||
2269 | - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it was | |
2270 | not properly padded with trailing '=' chars. This only affects a user that | |
2271 | need to use a password-authenticated proxy for an outgoing daemon-rsync | |
2272 | connection. | |
2273 | ||
2274 | - If we're transferring an empty directory to a new name, rsync no longer | |
2275 | forces `S_IWUSR` if it wasn't already set, nor does it accidentally leave it | |
2276 | set. | |
2277 | ||
2278 | - Fixed a bug in the debug output (`-vvvvv`) that could mention the wrong | |
2279 | checksum for the current file offset. | |
2280 | ||
2281 | - Rsync no longer allows a single directory to be copied over a non- directory | |
2282 | destination arg. | |
2283 | ||
2284 | ### ENHANCEMENTS: | |
2285 | ||
2286 | - Added the `--append` option that makes rsync append data onto files that are | |
2287 | longer on the source than the destination (this includes new files). | |
2288 | ||
2289 | - Added the `--min-size=SIZE` option to exclude small files from the transfer. | |
2290 | ||
2291 | - Added the `--compress-level` option to allow you to set how aggressive | |
2292 | rsync's compression should be (this option implies `--compress`). | |
2293 | ||
2294 | - Enhanced the parsing of the SIZE value for `--min-size` and `--max-size` to | |
2295 | allow easy entry of multiples of 1000 (instead of just multiples of 1024) | |
2296 | and off-by-one values too (e.g. `--max-size=8mb-1`). | |
2297 | ||
2298 | - Added the `--8-bit-output` (`-8`) option, which tells rsync to avoid | |
2299 | escaping high-bit characters that it thinks are unreadable in the current | |
2300 | locale. | |
2301 | ||
2302 | - The new option `--human-readable` (`-h`) changes the output of `--progress`, | |
2303 | `--stats`, and the end-of-run summary to be easier to read. If repeated, the | |
2304 | units become powers of 1024 instead of powers of 1000. (The old meaning of | |
2305 | `-h`, as a shorthand for `--help`, still works as long as you just use it on | |
2306 | its own, as in `rsync -h`.) | |
2307 | ||
2308 | - If lutimes() and/or lchmod() are around, use them to allow the preservation | |
2309 | of attributes on symlinks. | |
2310 | ||
2311 | - The `--link-dest` option now affects symlinks and devices (when possible). | |
2312 | ||
2313 | - Added two config items to the rsyncd.conf parsing: `pre-xfer exec` and | |
2314 | `post-xfer exec`. These allow a command to be specified on a per-module | |
2315 | basis that will be run before and/or after a daemon-mode transfer. (See the | |
2316 | man page for a list of the environment variables that are set with | |
2317 | information about the transfer.) | |
2318 | ||
2319 | - When using the `--relative` option, you can now insert a dot dir in the | |
2320 | source path to indicate where the replication of the source dirs should | |
2321 | start. For example, if you specify a source path of | |
2322 | rsync://host/module/foo/bar/./baz/dir with `-R`, rsync will now only | |
2323 | replicate the `baz/dir` part of the source path (note: a trailing dot dir is | |
2324 | unaffected unless it also has a trailing slash). | |
2325 | ||
2326 | - Added some new `--no-FOO` options that make it easier to override unwanted | |
2327 | implied or default options. For example, `-a --no-o` (aka `--archive | |
2328 | --no-owner`) can be used to turn off the preservation of file ownership that | |
2329 | is implied by `-a`. | |
2330 | ||
2331 | - Added the `--chmod=MODE` option that allows the destination permissions to | |
2332 | be changed from the source permissions. E.g. `--chmod=g+w,o-rwx` | |
2333 | ||
2334 | - Added the `incoming chmod` and `outgoing chmod` daemon options that allow a | |
2335 | module to specify what permissions changes should be applied to all files | |
2336 | copied to and from the daemon. | |
2337 | ||
2338 | - Allow the `--temp-dir` option to be specified when starting a daemon, which | |
2339 | sets the default temporary directory for incoming files. | |
2340 | ||
2341 | - If `--delete` is combined with `--dirs` without `--recursive`, rsync will | |
2342 | now delete in any directory whose content is being synchronized. | |
2343 | ||
2344 | - If `--backup` is combined with `--delete` without `--backup-dir` (and | |
2345 | without `--delete-excluded`), we add a `protect` filter-rule to ensure that | |
2346 | files with the backup suffix are not deleted. | |
2347 | ||
2348 | - The file-count stats that are output by `--progress` were improved to better | |
2349 | indicate what the numbers mean. For instance, the output: `(xfer#5, | |
2350 | to-check=8383/9999)` indicates that this was the fifth file to be | |
2351 | transferred, and we still need to check 8383 more files out of a total of | |
2352 | 9999. | |
2353 | ||
2354 | - The include/exclude code now allows a `dir/***` directive (with 3 trailing | |
2355 | stars) to match both the dir itself as well as all the content below the dir | |
2356 | (`dir/**` would not match the dir). | |
2357 | ||
2358 | - Added the `--prune-empty-dirs` (`-m`) option that makes the receiving rsync | |
2359 | discard empty chains of directories from the file-list. This makes it easier | |
2360 | to selectively copy files from a source hierarchy and end up with just the | |
2361 | directories needed to hold the resulting files. | |
2362 | ||
2363 | - If the `--itemize-changes` (`-i`) option is repeated, rsync now includes | |
2364 | unchanged files in the itemized output (similar to `-vv`, but without all | |
2365 | the other verbose messages that can get in the way). Of course, the client | |
2366 | must be version 2.6.7 for this to work, but the remote rsync only needs to | |
2367 | be 2.6.7 if you're pushing files. | |
2368 | ||
2369 | - Added the `--specials` option to tell rsync to copy non-device special files | |
2370 | (which rsync now attempts even as a normal user). The `--devices` option now | |
2371 | requests the copying of just devices (character and block). The `-D` option | |
2372 | still requests both (e.g. `--devices` and `--specials`), `-a` still implies | |
2373 | `-D`, and non-root users still get a silent downgrade that omits device | |
2374 | copying. | |
2375 | ||
2376 | - Added the `--super` option to make the receiver always attempt super-user | |
2377 | activities. This is useful for systems that allow things such as devices to | |
2378 | be created or ownership to be set without being UID 0, and is also useful | |
2379 | for someone who wants to ensure that errors will be output if the receiving | |
2380 | rsync isn't being run as root. | |
2381 | ||
2382 | - Added the `--sockopts` option for those few who want to customize the TCP | |
2383 | options used to contact a daemon rsync. | |
2384 | ||
2385 | - Added a way for the `--temp-dir` option to be combined with a partial-dir | |
2386 | setting that lets rsync avoid non-atomic updates (for those times when | |
2387 | `--temp-dir` is not being used because space is tight). | |
2388 | ||
2389 | - A new support script, files-to-excludes, will transform a list of files into | |
2390 | a set of include/exclude directives that will copy those files. | |
2391 | ||
2392 | - A new option, `--executability` (`-E`) can be used to preserve just the | |
2393 | execute bit on files, for those times when using the `--perms` option is not | |
2394 | desired. | |
2395 | ||
2396 | - The daemon now logs each connection and also each module-list request that | |
2397 | it receives. | |
2398 | ||
2399 | - New log-format options: %M (modtime), %U (uid), %G (gid), and %B (permission | |
2400 | bits, e.g. `rwxr-xrwt`). | |
2401 | ||
2402 | - The `--dry-run` option no longer forces the enabling of `--verbose`. | |
2403 | ||
2404 | - The `--remove-sent-files` option now does a better job of incrementally | |
2405 | removing the sent files on the sending side (older versions tended to clump | |
2406 | up all the removals at the end). | |
2407 | ||
2408 | - A daemon now supersedes its minimal SIGCHLD handler with the standard | |
2409 | PID-remembering version after forking. This ensures that the generator can | |
2410 | get the child-exit status from the receiver. | |
2411 | ||
2412 | - Use of the `--bwlimit` option no longer interferes with the remote rsync | |
2413 | sending error messages about invalid/refused options. | |
2414 | ||
2415 | - Rsync no longer returns a usage error when used with one local source arg | |
2416 | and no destination: this now implies the `--list-only` option, just like the | |
2417 | comparable situation with a remote source arg. | |
2418 | ||
2419 | - Added the `--copy-dirlinks` option, a more limited version of | |
2420 | `--copy-links`. | |
2421 | ||
2422 | - Various documentation improvements, including: a better synopsis, some | |
2423 | improved examples, a better discussion of the presence and absence of | |
2424 | `--perms` (including how it interacts with the new `--executability` and | |
2425 | `--chmod` options), an extended discussion of `--temp-dir`, an improved | |
2426 | discussion of `--partial-dir`, a better description of rsync's pattern | |
2427 | matching characters, an improved `--no-implied-dirs` section, and the | |
2428 | documenting of what the `--stats` option outputs. | |
2429 | ||
2430 | - Various new and updated diffs in the patches dir, including: acls.diff, | |
2431 | xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff. | |
2432 | ||
2433 | ### INTERNAL: | |
2434 | ||
2435 | - We now use sigaction() and sigprocmask() if possible, and fall back on | |
2436 | signal() if not. Using sigprocmask() ensures that rsync enables all the | |
2437 | signals that it needs, just in case it was started in a masked state. | |
2438 | ||
2439 | - Some buffer sizes were expanded a bit, particularly on systems where | |
2440 | MAXPATHLEN is overly small (e.g. cygwin). | |
2441 | ||
2442 | - If `io_printf()` tries to format more data than fits in the buffer, exit | |
2443 | with an error instead of transmitting a truncated buffer. | |
2444 | ||
2445 | - If a `va_copy` macro is defined, lib/snprintf.c will use it when defining | |
2446 | the `VA_COPY` macro. | |
2447 | ||
2448 | - Reduced the amount of stack memory needed for each level of directory | |
2449 | recursion by nearly MAXPATHLEN bytes. | |
2450 | ||
2451 | - The wildmatch function was extended to allow an array of strings to be | |
2452 | supplied as the string to match. This allows the exclude code to do less | |
2453 | string copying. | |
2454 | ||
2455 | - Got rid of the `safe_fname()` function (and all the myriad calls) and | |
2456 | replaced it with a new function in the log.c code that filters all the | |
2457 | output going to the terminal. | |
2458 | ||
2459 | - Unified the `f_name()` and the `f_name_to()` functions. | |
2460 | ||
2461 | - Improved the hash-table code the sender uses to handle checksums to make it | |
2462 | use slightly less memory and run just a little faster. | |
2463 | ||
2464 | ### DEVELOPER RELATED: | |
2465 | ||
2466 | - The diffs in the patches dir now require `patch -p1 <DIFF` instead of the | |
2467 | previous `-p0`. Also, the version included in the release tar now affect | |
2468 | generated files (e.g. configure, rsync.1, proto.h, etc.), so it is no longer | |
2469 | necessary to run autoconf and/or yodl unless you're applying a patch that | |
2470 | was checked out from CVS. | |
2471 | ||
2472 | - Several diffs in the patches dir now use the proper `--enable-FOO` configure | |
2473 | option instead of `--with-FOO` to turn on the inclusion of the newly patched | |
2474 | feature. | |
2475 | ||
2476 | - There is a new script, `prepare-source` than can be used to update the | |
2477 | various generated files (proto.h, configure, etc.) even before configure has | |
2478 | created the Makefile (this is mainly useful when patching the source with a | |
2479 | patch that doesn't affect generated files). | |
2480 | ||
2481 | - The testsuite now sets HOME so that it won't be affected by a file such as | |
2482 | ~/.popt. | |
2483 | ||

2486 | ||
2487 | # NEWS for rsync 2.6.6 (28 Jul 2005) | |
2488 | ||
2489 | Protocol: 29 (unchanged) | |
2490 | ||
2491 | ## Changes since 2.6.5: | |
2492 | ||
2493 | ### SECURITY FIXES: | |
2494 | ||
2495 | - The zlib code was upgraded to version 1.2.3 in order to make it more secure. | |
2496 | While the widely-publicized security problem in zlib 1.2.2 did not affect | |
2497 | rsync, another security problem surfaced that affects rsync's zlib 1.1.4. | |
2498 | ||
2499 | ### BUG FIXES: | |
2500 | ||
2501 | - The setting of `flist->high` in `clean_flist()` was wrong for an empty list. | |
2502 | This could cause `flist_find()` to crash in certain rare circumstances (e.g. | |
2503 | if just the right directory setup was around when `--fuzzy` was combined | |
2504 | with `--link-dest`). | |
2505 | ||
2506 | - The outputting of hard-linked files when verbosity was > 1 was not right: | |
2507 | (1) Without `-i` it would output the name of each hard-linked file as though | |
2508 | it had been changed; it now outputs a `is hard linked` message for the file. | |
2509 | (2) With `-i` it would output all dots for the unchanged attributes of a | |
2510 | hard-link; it now changes those dots to spaces, as is done for other totally | |
2511 | unchanged items. | |
2512 | ||
2513 | - When backing up a changed symlink or device, get rid of any old backup item | |
2514 | so that we don't get an `already exists` error. | |
2515 | ||
2516 | - A couple places that were comparing a local and a remote modification- time | |
2517 | were not honoring the `--modify-window` option. | |
2518 | ||
2519 | - Fixed a bug where the 'p' (permissions) itemized-changes flag might get set | |
2520 | too often (if some non-significant mode bits differed). | |
2521 | ||
2522 | - Fixed a really old, minor bug that could cause rsync to warn about being | |
2523 | unable to mkdir() a path that ends in `/.` because it just created the | |
2524 | directory (required `--relative`, `--no-implied-dirs`, a source path that | |
2525 | ended in either a trailing slash or a trailing `/.`, and a non-existing | |
2526 | destination dir to tickle the bug in a recent version). | |
2527 | ||
2528 | ### ENHANCEMENTS: | |
2529 | ||
2530 | - Made the `max verbosity` setting in the rsyncd.conf file settable on a | |
2531 | per-module basis (which now matches the documentation). | |
2532 | ||
2533 | - The support/rrsync script has been upgraded to verify the args of options | |
2534 | that take args (instead of rejecting any such options). The script was also | |
2535 | changed to try to be more secure and to fix a problem in the parsing of a | |
2536 | pull operation that has multiple sources. | |
2537 | ||
2538 | - Improved the documentation that explains the difference between a normal | |
2539 | daemon transfer and a daemon-over remote-shell transfer. | |
2540 | ||
2541 | - Some of the diffs supplied in the patches dir were fixed and/or improved. | |
2542 | ||
2543 | ### BUILD CHANGES: | |
2544 | ||
2545 | - Made configure define `NOBODY_USER` (currently hard-wired to `nobody`) and | |
2546 | `NOBODY_GROUP` (set to either `nobody` or `nogroup` depending on what we | |
2547 | find in the /etc/group file). | |
2548 | ||
2549 | - Added a test to the test suite, itemized.test, that tests the output of `-i` | |
2550 | (log-format w/%i) and some double-verbose messages. | |

2555 | # NEWS for rsync 2.6.5 (1 Jun 2005) | |
2556 | ||
2557 | Protocol: 29 (unchanged) | |
2558 | ||
2559 | ## Changes since 2.6.4: | |
2560 | ||
2561 | ### OUTPUT CHANGES: | |
2562 | ||
2563 | - Non-printable chars in filenames are now output using backslash- escaped | |
2564 | characters rather than '?'s. Any non-printable character is output using 3 | |
2565 | digits of octal (e.g. `\n` -> `\012`), and a backslash is now output as | |
2566 | `\\`. Rsync also uses your locale setting, which can make it treat fewer | |
2567 | high-bit characters as non-printable. | |
2568 | ||
2569 | - If rsync received an empty file-list when pulling files, it would output a | |
2570 | `nothing to do` message and exit with a 0 (success) exit status, even if the | |
2571 | remote rsync returned an error (it did not do this under the same conditions | |
2572 | when pushing files). This was changed to make the pulling behavior the same | |
2573 | as the pushing behavior: we now do the normal end-of-run outputting | |
2574 | (depending on options) and exit with the appropriate exit status. | |
2575 | ||
2576 | ### BUG FIXES: | |
2577 | ||
2578 | - A crash bug was fixed when a daemon had its `path` set to `/`, did not have | |
2579 | chroot enabled, and used some anchored excludes in the rsyncd.conf file. | |
2580 | ||
2581 | - Fixed a bug in the transfer of a single file when `-H` is specified (rsync | |
2582 | would either infinite loop or perhaps crash). | |
2583 | ||
2584 | - Fixed a case where the generator might try (and fail) to tweak the | |
2585 | write-permissions of a read-only directory in list-only mode (this only | |
2586 | caused an annoying warning message). | |
2587 | ||
2588 | - If `--compare-dest` or `--link-dest` uses a locally-copied file as the basis | |
2589 | for an updated version, log this better when `--verbose` or `-i` is in | |
2590 | effect. | |
2591 | ||
2592 | - Fixed the accidental disabling of `--backup` during the `--delete-after` | |
2593 | processing. | |
2594 | ||
2595 | - Restored the ability to use the `--address` option in client mode (in | |
2596 | addition to its use in daemon mode). | |
2597 | ||
2598 | - Make sure that some temporary progress information from the delete | |
2599 | processing does not get left on the screen when it is followed by a newline. | |
2600 | ||
2601 | - When `--existing` skips a directory with extra verbosity, refer to it as a | |
2602 | `directory`, not a `file`. | |
2603 | ||
2604 | - When transferring a single file to a different-named file, any generator | |
2605 | messages that are source-file related no longer refer to the file by the | |
2606 | destination filename. | |
2607 | ||
2608 | - Fixed a bug where hard-linking a group of files might fail if the generator | |
2609 | hasn't created a needed destination directory yet. | |
2610 | ||
2611 | - Fixed a bug where a hard-linked group of files that is newly-linked to a | |
2612 | file in a `--link-dest` dir doesn't link the files from the rest of the | |
2613 | cluster. | |
2614 | ||
2615 | - When deleting files with the `--one-file-system` (`-x`) option set, rsync no | |
2616 | longer tries to remove files from inside a mount-point on the receiving | |
2617 | side. Also, we don't complain about being unable to remove the mount-point | |
2618 | dir. | |
2619 | ||
2620 | - Fixed a compatibility problem when using `--cvs-ignore` (`-C`) and sending | |
2621 | files to an older rsync without using `--delete`. | |
2622 | ||
2623 | - Make sure that a `- !` or `+ !` include/exclude pattern does not trigger the | |
2624 | list-clearing action that is reserved for `!`. | |
2625 | ||
2626 | - Avoid a timeout in the generator when the sender/receiver aren't handling | |
2627 | the generator's checksum output quickly enough. | |
2628 | ||
2629 | - Fixed the omission of some directories in the delete processing when | |
2630 | `--relative` (`-R`) was combined with a source path that had a trailing | |
2631 | slash. | |
2632 | ||
2633 | - Fixed a case where rsync would erroneously delete some files and then | |
2634 | re-transfer them when the options `--relative` (`-R`) and `--recursive` | |
2635 | (`-r`) were both enabled (along with `--delete`) and a source path had a | |
2636 | trailing slash. | |
2637 | ||
2638 | - Make sure that `--max-size` doesn't affect a device or a symlink. | |
2639 | ||
2640 | - Make sure that a system with a really small MAXPATHLEN does not cause the | |
2641 | buffers in `readfd_unbuffered()` to be too small to receive normal messages. | |
2642 | (This mainly affected Cygwin.) | |
2643 | ||
2644 | - If a source pathname ends with a filename of `..`, treat it as if `../` had | |
2645 | been specified (so that we don't copy files to the parent dir of the | |
2646 | destination). | |
2647 | ||
2648 | - If `--delete` is combined with a file-listing rsync command (i.e. no | |
2649 | transfer is happening), avoid outputting a warning that we couldn't delete | |
2650 | anything. | |
2651 | ||
2652 | - If `--stats` is specified with `--delete-after`, ensure that all the | |
2653 | `deleting` messages are output before the statistics. | |
2654 | ||
2655 | - Improved one `if` in the deletion code that was only checking errno for | |
2656 | ENOTEMPTY when it should have also been checking for EEXIST (for | |
2657 | compatibility with OS variations). | |
2658 | ||
2659 | ### ENHANCEMENTS: | |
2660 | ||
2661 | - Added the `--only-write-batch=FILE` option that may be used (instead of | |
2662 | `--write-batch=FILE`) to create a batch file without doing any actual | |
2663 | updating of the destination. This allows you to divert all the file-updating | |
2664 | data away from a slow data link (as long as you are pushing the data to the | |
2665 | remote server when creating the batch). | |
2666 | ||
2667 | - When the generator is taking a long time to fill up its output buffer (e.g. | |
2668 | if the transferred files are few, small, or missing), it now periodically | |
2669 | flushes the output buffer so that the sender/receiver can get started on the | |
2670 | files sooner rather than later. | |
2671 | ||
2672 | - Improved the keep-alive code to handle a long silence between the sender and | |
2673 | the receiver that can occur when the sender is receiving the checksum data | |
2674 | for a large file. | |
2675 | ||
2676 | - Improved the auth-errors that are logged by the daemon to include some | |
2677 | information on why the authorization failed: wrong user, password mismatch, | |
2678 | etc. (The client-visible message is unchanged!) | |
2679 | ||
2680 | - Improved the client's handling of an `@ERROR` from a daemon so that it does | |
2681 | not complain about an unexpectedly closed socket (since we really did expect | |
2682 | the socket to close). | |
2683 | ||
2684 | - If the daemon can't open the log-file specified in rsyncd.conf, fall back to | |
2685 | using syslog and log an appropriate warning. This is better than what was | |
2686 | typically a totally silent (and fatal) failure (since a daemon is not | |
2687 | usually run with the `--no-detach` option that was necessary to see the | |
2688 | error on stderr). | |
2689 | ||
2690 | - The man pages now consistently refer to an rsync daemon as a `daemon` | |
2691 | instead of a `server` (to distinguish it from the server process in a | |
2692 | non-daemon transfer). | |
2693 | ||
2694 | - Made a small change to the rrsync script (restricted rsync -- in the support | |
2695 | dir) to make a read-only server reject all `--remove-*` options when sending | |
2696 | files (to future-proof it against the possibility of other similar options | |
2697 | being added at some point). | |
2698 | ||
2699 | ### INTERNAL: | |
2700 | ||
2701 | - Rsync now calls `setlocale(LC_CTYPE, "")`. This enables isprint() to better | |
2702 | discern which filename characters need to be escaped in messages (which | |
2703 | should result in fewer escaped characters in some locales). | |
2704 | ||
2705 | - Improved the naming of the log-file open/reopen/close functions. | |
2706 | ||
2707 | - Removed some protocol-compatibility code that was only needed to help | |
2708 | someone running a pre-release of 2.6.4. | |
2709 | ||
2710 | ### BUILD CHANGES: | |
2711 | ||
2712 | - Added configure option `--disable-locale` to disable any use of setlocale() | |
2713 | in the binary. | |
2714 | ||
2715 | - Fixed a bug in the `SUPPORT{,_HARD}_LINKS` #defines which prevented rsync | |
2716 | from being built without symlink or hard-link support. | |
2717 | ||
2718 | - Only #define `HAVE_REMSH` if it is going to be set to 1. | |
2719 | ||
2720 | - Configure now disables the use of mkstemp() under HP-UX (since they refuse | |
2721 | to fix its broken handling of large files). | |
2722 | ||
2723 | - Configure now explicitly checks for the lseek64() function so that the code | |
2724 | can use `HAVE_LSEEK64` instead of inferring lseek64()'s presence based on | |
2725 | the presence of the `off64_t` type. | |
2726 | ||
2727 | - Configure no longer mentions the change in the default remote-shell (from | |
2728 | rsh to ssh) that occurred for the 2.6.0 release. | |
2729 | ||
2730 | - Some minor enhancements to the test scripts. | |
2731 | ||
2732 | - Added a few new `*.diff` files to the patches dir, including a patch that | |
2733 | enables the optional copying of extended attributes. | |
2734 | ||

2738 | # NEWS for rsync 2.6.4 (30 March 2005) | |
2739 | ||
2740 | Protocol: 29 (changed) | |
2741 | ||
2742 | ## Changes since 2.6.3: | |
2743 | ||
2744 | ### OUTPUT CHANGES: | |
2745 | ||
2746 | - When rsync deletes a directory and outputs a verbose message about it, it | |
2747 | now appends a trailing slash to the name instead of (only sometimes) | |
2748 | outputting a preceding "directory " string. | |
2749 | ||
2750 | - The `--stats` output will contain file-list time-statistics if both sides | |
2751 | are 2.6.4, or if the local side is 2.6.4 and the files are being pushed | |
2752 | (since the stats come from the sending side). (Requires protocol 29 for a | |
2753 | pull.) | |
2754 | ||
2755 | - The `%o` (operation) log-format escape now has a third value (besides `send` | |
2756 | and `recv`): `del.` (with trailing dot to make it 4 chars). This changes | |
2757 | the way deletions are logged in the daemon's log file. | |
2758 | ||
2759 | - When the `--log-format` option is combined with `--verbose`, rsync now | |
2760 | avoids outputting the name of the file twice in most circumstances. As long | |
2761 | as the `--log-format` item does not refer to any post-transfer items (such | |
2762 | as %b or %c), the `--log-format` message is output prior to the transfer, so | |
2763 | `--verbose` is now the equivalent of a `--log-format` of '%n%L' (which | |
2764 | outputs the name and any link info). If the log output must occur after the | |
2765 | transfer to be complete, the only time the name is also output prior to the | |
2766 | transfer is when `--progress` was specified (so that the name will precede | |
2767 | the progress stats, and the full `--log-format` output will come after). | |
2768 | ||
2769 | - Non-printable characters in filenames are replaced with a '?' to avoid | |
2770 | corrupting the screen or generating empty lines in the output. | |
2771 | ||
2772 | ### BUG FIXES: | |
2773 | ||
2774 | - Restore the list-clearing behavior of `!` in a .cvsignore file (2.6.3 was | |
2775 | only treating it as a special token in an rsync include/exclude file). | |
2776 | ||
2777 | - The combination of `--verbose` and `--dry-run` now mentions the full list of | |
2778 | changes that would be output without `--dry-run`. | |
2779 | ||
2780 | - Avoid a mkdir warning when removing a directory in the destination that | |
2781 | already exists in the `--backup-dir`. | |
2782 | ||
2783 | - An OS that has a binary mode for its files (such as cygwin) needed | |
2784 | `setmode(fd, O_BINARY)` called on the temp-file we opened with mkstemp(). | |
2785 | (Fix derived from cygwin's 2.6.3 rsync package.) | |
2786 | ||
2787 | - Fixed a potential hang when verbosity is high, the client side is the | |
2788 | sender, and the file-list is large. | |
2789 | ||
2790 | - Fixed a potential protocol-corrupting bug where the generator could merge a | |
2791 | message from the receiver into the middle of a multiplexed packet of data if | |
2792 | only part of that data had been written out to the socket when the message | |
2793 | from the generator arrived. | |
2794 | ||
2795 | - We now check if the OS doesn't support using mknod() for creating FIFOs and | |
2796 | sockets, and compile-in some compatibility code using mkfifo() and socket() | |
2797 | when necessary. | |
2798 | ||
2799 | - Fixed an off-by-one error in the handling of `--max-delete=N`. Also, if the | |
2800 | `--max-delete` limit is exceeded during a run, we now output a warning about | |
2801 | this at the end of the run and exit with a new error code (25). | |
2802 | ||
2803 | - One place in the code wasn't checking if fork() failed. | |
2804 | ||
2805 | - The `ignore nonreadable` daemon parameter used to erroneously affect | |
2806 | readable symlinks that pointed to a non-existent file. | |
2807 | ||
2808 | - If the OS does not have lchown() and a chown() of a symlink will affect the | |
2809 | referent of a symlink (as it should), we no longer try to set the user and | |
2810 | group of a symlink. | |
2811 | ||
2812 | - The generator now properly runs the hard-link loop and the dir-time | |
2813 | rewriting loop after we're sure that the redo phase is complete. | |
2814 | ||
2815 | - When `--backup` was specified with `--partial-dir=DIR`, where DIR is a | |
2816 | relative path, the backup code was erroneously trying to backup a file that | |
2817 | was put into the partial-dir. | |
2818 | ||
2819 | - If a file gets resent in a single transfer and the `--backup` option is | |
2820 | enabled along with `--inplace`, rsync no longer performs a duplicate backup | |
2821 | (it used to overwrite the first backup with the failed file). | |
2822 | ||
2823 | - One call to `flush_write_file()` was not being checked for an error. | |
2824 | ||
2825 | - The `--no-relative` option was not being sent from the client to a server | |
2826 | sender. | |
2827 | ||
2828 | - If an rsync daemon specified `dont compress = ...` for a file and the client | |
2829 | tried to specify `--compress`, the libz code was not handling a compression | |
2830 | level of 0 properly. This could cause a transfer failure if the block-size | |
2831 | for a file was large enough (e.g. rsync might have exited with an error for | |
2832 | large files). | |
2833 | ||
2834 | - Fixed a bug that would sometimes surface when using `--compress` and sending | |
2835 | a file with a block-size larger than 64K (either manually specified, or | |
2836 | computed due to the file being really large). Prior versions of rsync would | |
2837 | sometimes fail to decompress the data properly, and thus the transferred | |
2838 | file would fail its verification. | |
2839 | ||
2840 | - If a daemon can't open the specified log file (i.e. syslog is not being | |
2841 | used), die without crashing. We also output an error about the failure on | |
2842 | stderr (which will only be seen if `--no-detach` was specified) and exit | |
2843 | with a new error code (6). | |
2844 | ||
2845 | - A local transfer no longer duplicates all its include/exclude options (since | |
2846 | the forked process already has a copy of the exclude list, there's no need | |
2847 | to send them a set of duplicates). | |
2848 | ||
2849 | - The output of the items that are being updated by the generator (dirs, | |
2850 | symlinks, devices) is now intermingled in the proper order with the output | |
2851 | from the items that the receiver is updating (regular files) when pulling. | |
2852 | This misordering was particularly bad when `--progress` was specified. | |
2853 | (Requires protocol 29.) | |
2854 | ||
2855 | - When `--timeout` is specified, lulls that occur in the transfer while the | |
2856 | generator is doing work that does not generate socket traffic (looking for | |
2857 | changed files, deleting files, doing directory-time touch-ups, etc.) will | |
2858 | cause a new keep-alive packet to be sent that should keep the transfer going | |
2859 | as long as the generator continues to make progress. (Requires protocol 29.) | |
2860 | ||
2861 | - The stat size of a device is not added to the total file size of the items | |
2862 | in the transfer (the size might be undefined on some OSes). | |
2863 | ||
2864 | - Fixed a problem with refused-option messages sometimes not making it back to | |
2865 | the client side when a remote `--files-from` was in effect and the daemon | |
2866 | was the receiver. | |
2867 | ||
2868 | - The `--compare-dest` option was not updating a file that differed in (the | |
2869 | preserved) attributes from the version in the compare-dest DIR. | |
2870 | ||
2871 | - When rsync is copying files into a write-protected directory, fixed the | |
2872 | change-report output for the directory so that we don't report an identical | |
2873 | directory as changed. | |
2874 | ||
2875 | ### ENHANCEMENTS: | |
2876 | ||
2877 | - Rsync now supports popt's option aliases, which means that you can use | |
2878 | /etc/popt and/or ~/.popt to create your own option aliases. | |
2879 | ||
2880 | - Added the `--delete-during` (`--del`) option which will delete files from | |
2881 | the receiving side incrementally as each directory in the transfer is being | |
2882 | processed. This makes it more efficient than the default, | |
2883 | before-the-transfer behavior, which is now also available as | |
2884 | `--delete-before` (and is still the default `--delete-WHEN` option that will | |
2885 | be chosen if `--delete` or `--delete-excluded` is specified without a | |
2886 | `--delete-WHEN` choice). All the `--del*` options infer `--delete`, so an | |
2887 | rsync daemon that refuses `delete` will still refuse to allow any | |
2888 | file-deleting options (including the new `--remove-sent-files` option). | |
2889 | ||
2890 | - All the `--delete-WHEN` options are now more memory efficient: Previously an | |
2891 | duplicate set of file-list objects was created on the receiving side for the | |
2892 | entire destination hierarchy. The new algorithm only creates one directory | |
2893 | of objects at a time (for files inside the transfer). | |
2894 | ||
2895 | - Added the `--copy-dest` option, which works like `--link-dest` except that | |
2896 | it locally copies identical files instead of hard-linking them. | |
2897 | ||
2898 | - Added support for specifying multiple `--compare-dest`, `--copy-dest`, or | |
2899 | `--link-dest` options, but only of a single type. (Promoted from the patches | |
2900 | dir and enhanced.) (Requires protocol 29.) | |
2901 | ||
2902 | - Added the `--max-size` option. (Promoted from the patches dir.) | |
2903 | ||
2904 | - The daemon-mode options are now separated from the normal rsync options so | |
2905 | that they can't be mixed together. This makes it impossible to start a | |
2906 | daemon that has improper default option values (which could cause problems | |
2907 | when a client connects, such as hanging or crashing). | |
2908 | ||
2909 | - The `--bwlimit` option may now be used in combination with `--daemon` to | |
2910 | specify both a default value for the daemon side and a value that cannot be | |
2911 | exceeded by a user-specified `--bwlimit` option. | |
2912 | ||
2913 | - Added the `port` parameter to the rsyncd.conf file. (Promoted from the | |
2914 | patches dir.) Also added `address`. The command-line options take precedence | |
2915 | over a config-file option, as expected. | |
2916 | ||
2917 | - In `_exit_cleanup()`: when we are exiting with a partially-received file, we | |
2918 | now flush any data in the write-cache before closing the partial file. | |
2919 | ||
2920 | - The `--inplace` support was enhanced to work with `--compare-dest`, | |
2921 | `--link-dest`, and (the new) `--copy-dest` options. (Requires protocol 29.) | |
2922 | ||
2923 | - Added the `--dirs` (`-d`) option for an easier way to copy directories | |
2924 | without recursion. Any directories that are encountered are created on the | |
2925 | destination. Specifying a directory with a trailing slash copies its | |
2926 | immediate contents to the destination. | |
2927 | ||
2928 | - The `--files-from` option now implies `--dirs` (`-d`). | |
2929 | ||
2930 | - Added the `--list-only` option, which is mainly a way for the client to put | |
2931 | the server into listing mode without needing to resort to any internal | |
2932 | option kluges (e.g. the age-old use of `-r --exclude='/*/*'` for a | |
2933 | non-recursive listing). This option is used automatically (behind the | |
2934 | scenes) when a modern rsync speaks to a modern daemon, but may also be | |
2935 | specified manually if you want to force the use of the `--list-only` option | |
2936 | over a remote-shell connection. | |
2937 | ||
2938 | - Added the `--omit-dir-times` (`-O`) option, which will avoid updating the | |
2939 | modified time for directories when `--times` was specified. This option will | |
2940 | avoid an extra pass through the file-list at the end of the transfer (to | |
2941 | tweak all the directory times), which may provide an appreciable speedup for | |
2942 | a really large transfer. (Promoted from the patches dir.) | |
2943 | ||
2944 | - Added the `--filter` (`-f`) option and its helper option, `-F`. Filter rules | |
2945 | are an extension to the existing include/exclude handling that also supports | |
2946 | nested filter files as well as per-directory filter files (like .cvsignore, | |
2947 | but with full filter-rule parsing). This new option was chosen in order to | |
2948 | ensure that all existing include/exclude processing remained 100% compatible | |
2949 | with older versions. Protocol 29 is needed for full filter-rule support, but | |
2950 | backward-compatible rules work with earlier protocol versions. (Promoted | |
2951 | from the patches dir and enhanced.) | |
2952 | ||
2953 | - Added the `--delay-updates` option that puts all updated files into a | |
2954 | temporary directory (by default `.~tmp~`, but settable via the | |
2955 | `--partial-dir=DIR` option) until the end of the transfer. This makes the | |
2956 | updates a little more atomic for a large transfer. | |
2957 | ||
2958 | - If rsync is put into the background, any output from `--progress` is | |
2959 | reduced. | |
2960 | ||
2961 | - Documented the `max verbosity` setting for rsyncd.conf. (This setting was | |
2962 | added a couple releases ago, but left undocumented.) | |
2963 | ||
2964 | - The sender and the generator now double-check the file-list index they are | |
2965 | given, and refuse to try to do a file transfer on a non-file index (since | |
2966 | that would indicate that something had gone very wrong). | |
2967 | ||
2968 | - Added the `--itemize-changes` (`-i`) option, which is a way to output a more | |
2969 | detailed list of what files changed and in what way. The effect is the same | |
2970 | as specifying a `--log-format` of `%i %n%L` (see both the rsync and | |
2971 | rsyncd.conf manpages). Works with `--dry-run` too. | |
2972 | ||
2973 | - Added the `--fuzzy` (`-y`) option, which attempts to find a basis file for a | |
2974 | file that is being created from scratch. The current algorithm only looks in | |
2975 | the destination directory for the created file, but it does attempt to find | |
2976 | a match based on size/mod-time (in case the file was renamed with no other | |
2977 | changes) as well as based on a fuzzy name-matching algorithm. This option | |
2978 | requires protocol 29 because it needs the new file-sorting order. (Promoted | |
2979 | from patches dir and enhanced.) (Requires protocol 29.) | |
2980 | ||
2981 | - Added the `--remove-sent-files` option, which lets you move files between | |
2982 | systems. | |
2983 | ||
2984 | - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal enclosed | |
2985 | in '[' and ']' (e.g. `[::1]`). (We already allowed IPv6 literals in the | |
2986 | rsync://HOST:PORT/PATH format.) | |
2987 | ||
2988 | - When rsync recurses to build the file list, it no longer keeps open one or | |
2989 | more directory handles from the dir's parent dirs. | |
2990 | ||
2991 | - When building under windows, the default for `--daemon` is now to avoid | |
2992 | detaching, requiring the new `--detach` option to force rsync to detach. | |
2993 | ||
2994 | - The `--dry-run` option can now be combined with either `--write-batch` or | |
2995 | `--read-batch`, allowing you to run a do-nothing test command to see what | |
2996 | would happen without `--dry-run`. | |
2997 | ||
2998 | - The daemon's `read only` config item now sets an internal `read_only` | |
2999 | variable that makes extra sure that no write/delete calls on the read-only | |
3000 | side can succeed. | |
3001 | ||
3002 | - The log-format % escapes can now have a numeric field width in between the % | |
3003 | and the escape letter (e.g. `%-40n %08p`). | |
3004 | ||
3005 | - Improved the option descriptions in the `--help` text. | |
3006 | ||
3007 | ### SUPPORT FILES: | |
3008 | ||
3009 | - Added atomic-rsync to the support dir: a perl script that will transfer some | |
3010 | files using rsync, and then move the updated files into place all at once at | |
3011 | the end of the transfer. Only works when pulling, and uses `--link-dest` and | |
3012 | a parallel hierarchy of files to effect its update. | |
3013 | ||
3014 | - Added mnt-excl to the support dir: a perl script that takes the /proc/mounts | |
3015 | file and translates it into a set of excludes that will exclude all mount | |
3016 | points (even mapped mounts to the same disk). The excludes are made relative | |
3017 | to the specified source dir and properly anchored. | |
3018 | ||
3019 | - Added savetransfer.c to the support dir: a C program that can make a copy of | |
3020 | all the data that flows over the wire. This lets you test for data | |
3021 | corruption (by saving the data on both the sending side and the receiving | |
3022 | side) and provides one way to debug a protocol error. | |
3023 | ||
3024 | - Added rrsync to the support dir: this is an updated version of Joe Smith's | |
3025 | restricted rsync perl script. This helps to ensure that only certain rsync | |
3026 | commands can be run by an ssh invocation. | |
3027 | ||
3028 | ### INTERNAL: | |
3029 | ||
3030 | - Added better checking of the checksum-header values that come over the | |
3031 | socket. | |
3032 | ||
3033 | - Merged a variety of file-deleting functions into a single function so that | |
3034 | it is easier to maintain. | |
3035 | ||
3036 | - Improved the type of some variables (particularly blocksize vars) for | |
3037 | consistency and proper size. | |
3038 | ||
3039 | - Got rid of the uint64 type (which we didn't need). | |
3040 | ||
3041 | - Use a slightly more compatible set of core #include directives. | |
3042 | ||
3043 | - Defined int32 in a way that ensures that the build dies if we can't find a | |
3044 | variable with at least 32 bits. | |
3045 | ||
3046 | ### PROTOCOL DIFFERENCES FOR VERSION 29: | |
3047 | ||
3048 | - A 16-bit flag-word is transmitted after every file-list index. This | |
3049 | indicates what is changing between the sender and the receiver. The | |
3050 | generator now transmits an index and a flag-word to indicate when dirs and | |
3051 | symlinks have changed (instead of producing a message), which makes the | |
3052 | outputting of the information more consistent and less prone to screen | |
3053 | corruption (because the local receiver/sender is now outputting all the | |
3054 | file-change info messages). | |
3055 | ||
3056 | - If a file is being hard-linked, the `ITEM_XNAME_FOLLOWS` bit is enabled in | |
3057 | the flag-word and the name of the file that was linked immediately follows | |
3058 | in vstring format (see below). | |
3059 | ||
3060 | - If a file is being transferred with an alternate-basis file, the | |
3061 | `ITEM_BASIS_TYPE_FOLLOWS` bit is enabled in the flag-word and a single byte | |
3062 | follows, indicating what type of basis file was chosen. If that indicates | |
3063 | that a fuzzy-match was selected, the `ITEM_XNAME_FOLLOWS` bit is set in the | |
3064 | flag-word and the name of the match in vstring format follows the basis | |
3065 | byte. A vstring is a variable length string that has its size written prior | |
3066 | to the string, and no terminating null. If the string is from 1-127 bytes, | |
3067 | the length is a single byte. If it is from 128-32767 bytes, the length is | |
3068 | written as ((len >> 8) | 0x80) followed by (len % 0x100). | |
3069 | ||
3070 | - The sending of exclude names is done using filter-rule syntax. This means | |
3071 | that all names have a prefixed rule indicator, even excludes (which used to | |
3072 | be sent as a bare pattern, when possible). The `-C` option will include the | |
3073 | per-dir .cvsignore merge file in the list of filter rules so it is | |
3074 | positioned correctly (unlike in some older transfer scenarios). | |
3075 | ||
3076 | - Rsync sorts the filename list in a different way: it sorts the subdir names | |
3077 | after the non-subdir names for each dir's contents, and it always puts a | |
3078 | dir's contents immediately after the dir's name in the list. (Previously an | |
3079 | item named `foo.txt` would sort in between directory `foo/` and `foo/bar`.) | |
3080 | ||
3081 | - When talking to a protocol 29 rsync daemon, a list-only request is able to | |
3082 | note this before the options are sent over the wire and the new | |
3083 | `--list-only` option is included in the options. | |
3084 | ||
3085 | - When the `--stats` bytes are sent over the wire (or stored in a batch), they | |
3086 | now include two elapsed-time values: one for how long it took to build the | |
3087 | file-list, and one for how long it took to send it over the wire (each | |
3088 | expressed in thousandths of a second). | |
3089 | ||
3090 | - When `--delete-excluded` is specified with some filter rules (AKA excludes), | |
3091 | a client sender will now initiate a send of the rules to the receiver (older | |
3092 | protocols used to omit the sending of excludes in this situation since there | |
3093 | were no receiver-specific rules that survived `--delete-excluded` back | |
3094 | then). Note that, as with all the filter-list sending, only items that are | |
3095 | significant to the other side will actually be sent over the wire, so the | |
3096 | filter-rule list that is sent in this scenario is often empty. | |
3097 | ||
3098 | - An index equal to the file-list count is sent as a keep-alive packet from | |
3099 | the generator to the sender, which then forwards it on to the receiver. This | |
3100 | normally invalid index is only a valid keep-alive packet if the 16-bit | |
3101 | flag-word that follows it contains a single bit (`ITEM_IS_NEW`, which is | |
3102 | normally an illegal flag to appear alone). | |
3103 | ||
3104 | - A protocol-29 batch file includes a bit for the setting of the `--dirs` | |
3105 | option and for the setting of the `--compress` option. Also, the shell | |
3106 | script created by `--write-batch` will use the `--filter` option instead of | |
3107 | `--exclude-from` to capture any filter rules. | |
3108 | ||
3109 | ### BUILD CHANGES: | |
3110 | ||
3111 | - Handle an operating system that use mkdev() in place of makedev(). | |
3112 | ||
3113 | - Improved configure to better handle cross-compiling. | |
3114 | ||

3118 | # NEWS for rsync 2.6.3 (30 Sep 2004) | |
3119 | ||
3120 | Protocol: 28 (unchanged) | |
3121 | ||
3122 | ## Changes since 2.6.2: | |
3123 | ||
3124 | ### SECURITY FIXES: | |
3125 | ||
3126 | - A bug in the `sanitize_path` routine (which affects a non-chrooted rsync | |
3127 | daemon) could allow a user to craft a pathname that would get transformed | |
3128 | into an absolute path for certain options (but not for file-transfer names). | |
3129 | If you're running an rsync daemon with chroot disabled, **please upgrade**, | |
3130 | ESPECIALLY if the user privs you run rsync under is anything above `nobody`. | |
3131 | ||
3132 | OUTPUT CHANGES (ATTN: those using a script to parse the verbose output): | |
3133 | ||
3134 | - Please note that the 2-line footer (output when verbose) now uses the term | |
3135 | `sent` instead of `wrote` and `received` instead of `read`. If you are not | |
3136 | parsing the numeric values out of this footer, a script would be better off | |
3137 | using the empty line prior to the footer as the indicator that the verbose | |
3138 | output is over. | |
3139 | ||
3140 | - The output from the `--stats` option was similarly affected to change | |
3141 | `written` to `sent` and `read` to `received`. | |
3142 | ||
3143 | - Rsync ensures that a filename that contains a newline gets mentioned with | |
3144 | each newline transformed into a question mark (which prevents a filename | |
3145 | from causing an empty line to be output). | |
3146 | ||
3147 | - The `backed up ...` message that is output when at least 2 `--verbose` | |
3148 | options are specified is now the same both with and without the | |
3149 | `--backup-dir` option. | |
3150 | ||
3151 | ### BUG FIXES: | |
3152 | ||
3153 | - Fixed a crash bug that might appear when `--delete` was used and multiple | |
3154 | source directories were specified. | |
3155 | ||
3156 | - Fixed a 32-bit truncation of the file length when generating the checksums. | |
3157 | ||
3158 | - The `--backup` code no longer attempts to create some directories over and | |
3159 | over again (generating warnings along the way). | |
3160 | ||
3161 | - Fixed a bug in the reading of the secrets file (by the daemon) and the | |
3162 | password file (by the client): the files no longer need to be terminated by | |
3163 | a newline for their content to be read in. | |
3164 | ||
3165 | - If a file has a read error on the sending side or the reconstructed data | |
3166 | doesn't match the expected checksum (perhaps due to the basis file changing | |
3167 | during the transfer), the receiver will no longer retain the resulting file | |
3168 | unless the `--partial` option was specified. (Note: for the read-error | |
3169 | detection to work, neither side can be older than 2.6.3 -- older receivers | |
3170 | will always retain the file, and older senders don't tell the receiver that | |
3171 | the file had a read error.) | |
3172 | ||
3173 | - If a file gets resent in a single transfer and the `--backup` option is | |
3174 | enabled, rsync no longer performs a duplicate backup (it used to overwrite | |
3175 | the original file in the backup area). | |
3176 | ||
3177 | - Files specified in the daemon's `exclude` or `exclude from` config items are | |
3178 | now excluded from being uploaded (assuming that the module allows uploading | |
3179 | at all) in addition to the old download exclusion. | |
3180 | ||
3181 | - Got rid of a potential hang in the receiver when near the end of a phase. | |
3182 | ||
3183 | - When using `--backup` without a `--backup-dir`, rsync no longer preserves | |
3184 | the modify time on directories. This avoids confusing NFS. | |
3185 | ||
3186 | - When `--copy-links` (`-L`) is specified, we now output a separate error for | |
3187 | a symlink that has no referent instead of claiming that a file `vanished`. | |
3188 | ||
3189 | - The `--copy-links` (`-L`) option no longer has the side-effect of telling | |
3190 | the receiving side to follow symlinks. See the `--keep-dirlinks` option | |
3191 | (mentioned below) for a way to specify that behavior. | |
3192 | ||
3193 | - Error messages from the daemon server's option-parsing (such as refused | |
3194 | options) are now successfully transferred back to the client (the server | |
3195 | used to fail to send the message because the socket wasn't in the right | |
3196 | state for the message to get through). | |
3197 | ||
3198 | - Most transfer errors that occur during a daemon transfer are now returned to | |
3199 | the user in addition to being logged (some messages are intended to be | |
3200 | daemon-only and are not affected by this). | |
3201 | ||
3202 | - Fixed a bug in the daemon authentication code when using one of the | |
3203 | batch-processing options. | |
3204 | ||
3205 | - We try to work around some buggy IPv6 implementations that fail to implement | |
3206 | `IPV6_V6ONLY`. This should fix the `address in use` error that some daemons | |
3207 | get when running on an OS with a buggy IPv6 implementation. Also, if the new | |
3208 | code gets this error, we might suggest that the user specify `--ipv4` or | |
3209 | `--ipv6` (if we think it will help). | |
3210 | ||
3211 | - When the remote rsync dies, make a better effort to recover any error | |
3212 | messages it may have sent before dying (the local rsync used to just die | |
3213 | with a socket-write error). | |
3214 | ||
3215 | - When using `--delete` and a `--backup-dir` that contains files that are | |
3216 | hard-linked to their destination equivalents, rsync now makes sure that | |
3217 | removed files really get removed (avoids a really weird rename() behavior). | |
3218 | ||
3219 | - Avoid a bogus run-time complaint about a lack of 64-bit integers when the | |
3220 | int64 type is defined as an `off_t` and it actually has 64-bits. | |
3221 | ||
3222 | - Added a configure check for open64() without mkstemp64() so that we can | |
3223 | avoid using mkstemp() when such a combination is encountered. This bypasses | |
3224 | a problem writing out large temp files on OSes such as AIX and HP-UX. | |
3225 | ||
3226 | - Fixed an age-old crash problem with `--read-batch` on a local copy (rsync | |
3227 | was improperly assuming `--whole-file` for the local copy). | |
3228 | ||
3229 | - When `--dry-run` (`-n`) is used and the destination directory does not | |
3230 | exist, rsync now produces a correct report of files that would be sent | |
3231 | instead of dying with a chdir() error. | |
3232 | ||
3233 | - Fixed a bug that could cause a slow-to-connect rsync daemon to die with an | |
3234 | error instead of waiting for the connection to finish. | |
3235 | ||
3236 | - Fixed an ssh interaction that could cause output to be lost when the user | |
3237 | chose to combine the output of rsync's stdout and stderr (e.g. using the | |
3238 | `2>&1`). | |
3239 | ||
3240 | - Fixed an option-parsing bug when `--files-from` got passed to a daemon. | |
3241 | ||
3242 | ### ENHANCEMENTS: | |
3243 | ||
3244 | - Added the `--partial-dir=DIR` option that lets you specify where to | |
3245 | (temporarily) put a partially transferred file (instead of over- writing the | |
3246 | destination file). E.g. `--partial-dir=.rsync-partial` Also added support | |
3247 | for the `RSYNC_PARTIAL_DIR` environment variable that, when found, | |
3248 | transforms a regular `--partial` option (such as the convenient `-P` option) | |
3249 | into one that also specifies a directory. | |
3250 | ||
3251 | - Added `--keep-dirlinks` (`-K`), which allows you to symlink a directory onto | |
3252 | another partition on the receiving side and have rsync treat it as matching | |
3253 | a normal directory from the sender. | |
3254 | ||
3255 | - Added the `--inplace` option that tells rsync to write each destination file | |
3256 | without using a temporary file. The matching of existing data in the | |
3257 | destination file can be severely limited by this, but there are also cases | |
3258 | where this is more efficient (such as appending data). Use only when needed | |
3259 | (see the man page for more details). | |
3260 | ||
3261 | - Added the `write only` option for the daemon's config file. | |
3262 | ||
3263 | - Added long-option names for `-4` and `-6` (namely `--ipv4` and `--ipv6`) and | |
3264 | documented all these options in the man page. | |
3265 | ||
3266 | - Improved the handling of the `--bwlimit` option so that it's less bursty, | |
3267 | more accurate, and works properly over a larger range of values. | |
3268 | ||
3269 | - The rsync daemon-over-ssh code now looks for `SSH_CONNECTION` and | |
3270 | `SSH2_CLIENT` in addition to `SSH_CLIENT` to figure out the IP address. | |
3271 | ||
3272 | - Added the `--checksum-seed=N` option for advanced users. | |
3273 | ||
3274 | - Batch writing/reading has a brand-new implementation that is simpler, fixes | |
3275 | a few weird problems with the old code (such as no longer sprinkling the | |
3276 | batch files into different dirs or even onto different systems), and is much | |
3277 | less intrusive into the code (making it easier to maintain for the future). | |
3278 | The new code generates just one data file instead of three, which makes it | |
3279 | possible to read the batch on stdin via a remote shell. Also, the old | |
3280 | requirement of forcing the same fixed checksum-seed for all batch processing | |
3281 | has been removed. | |
3282 | ||
3283 | - If an rsync daemon has a module set with `list = no` (which hides its | |
3284 | presence in the list of available modules), a user that fails to | |
3285 | authenticate gets the same `unknown module` error that they would get if the | |
3286 | module were actually unknown (while still logging the real error to the | |
3287 | daemon's log file). This prevents fishing for module names. | |
3288 | ||
3289 | - The daemon's `refuse options` config item now allows you to match option | |
3290 | names using wildcards and/or the single-letter option names. | |
3291 | ||
3292 | - Each transferred file now gets its permissions and modified-time updated | |
3293 | before the temp-file gets moved into place. Previously, the finished file | |
3294 | would have a very brief window where its permissions disallowed all group | |
3295 | and world access. | |
3296 | ||
3297 | - Added the ability to parse a literal IPv6 address in an `rsync:` URL (e.g. | |
3298 | rsync://[2001:638:500:101::21]:873/module/dir). | |
3299 | ||
3300 | - The daemon's wildcard expanding code can now handle more than 1000 filenames | |
3301 | (it's now limited by memory instead of having a hard-wired limit). | |
3302 | ||
3303 | ### INTERNAL: | |
3304 | ||
3305 | - Some cleanup in the exclude code has saved some per-exclude memory and made | |
3306 | the code easier to maintain. | |
3307 | ||
3308 | - Improved the argv-overflow checking for a remote command that has a lot of | |
3309 | args. | |
3310 | ||
3311 | - Use rsyserr() in the various places that were still calling rprintf() with | |
3312 | strerror() as an arg. | |
3313 | ||
3314 | - If an rsync daemon is listening on multiple sockets (to handle both IPv4 and | |
3315 | IPv6 to a single port), we now close all the unneeded file handles after we | |
3316 | accept a connection (we used to close just one of them). | |
3317 | ||
3318 | - Optimized the handling of larger block sizes (rsync used to slow to a crawl | |
3319 | if the block size got too large). | |
3320 | ||
3321 | - Optimized away a loop in `hash_search()`. | |
3322 | ||
3323 | - Some improvements to the `sanitize_path()` and `clean_fname()` functions | |
3324 | makes them more efficient and produce better results (while still being | |
3325 | compatible with the file-name cleaning that gets done on both sides when | |
3326 | sending the file-list). | |
3327 | ||
3328 | - Got rid of `alloc_sanitize_path()` after adding a destination-buffer arg to | |
3329 | `sanitize_path()` made it possible to put all the former's functionality | |
3330 | into the latter. | |
3331 | ||
3332 | - The file-list that is output when at least 4 verbose options are specified | |
3333 | reports the uid value on the sender even when rsync is not running as root | |
3334 | (since we might be sending to a root receiver). | |
3335 | ||
3336 | ### BUILD CHANGES: | |
3337 | ||
3338 | - Added a `gen` target to rebuild most of the generated files, including | |
3339 | configure, config.h.in, the man pages, and proto.h. | |
3340 | ||
3341 | - If `make proto` doesn't find some changes in the prototypes, the proto.h | |
3342 | file is left untouched (its time-stamp used to always be updated). | |
3343 | ||
f6df3708 WD |
3344 | - The variable `$STRIP` (that is optionally set by the install-strip target's |
3345 | rule) was changed to `$INSTALL_STRIP` because some systems have `$STRIP` | |
87bca719 WD |
3346 | already set in the environment. |
3347 | ||
3348 | - Fixed a build problem when `SUPPORT_HARD_LINKS` isn't defined. | |
3349 | ||
3350 | - When cross-compiling, the gettimeofday() function is now assumed to be a | |
3351 | modern version that takes two-args (since we can't test it). | |
3352 | ||
3353 | ### DEVELOPER RELATED: | |
3354 | ||
3355 | - The scripts in the testsuite dir were cleaned up a bit and a few new tests | |
3356 | added. | |
3357 | ||
3358 | - Some new diffs were added to the patches dir, and some accepted ones were | |
3359 | removed. | |

3364 | # NEWS for rsync 2.6.2 (30 Apr 2004) | |
3365 | ||
3366 | Protocol: 28 (unchanged) | |
3367 | ||
3368 | ## Changes since 2.6.1: | |
3369 | ||
3370 | ### BUG FIXES: | |
3371 | ||
3372 | - Fixed a major bug in the sorting of the filenames when `--relative` is used | |
3373 | for some sources (just sources such as `/` and `/*` were affected). This fix | |
3374 | ensures that we ask for the right file-list item when requesting changes | |
3375 | from the sender. | |
3376 | ||
3377 | - Rsync now checks the return value of the close() function to better report | |
3378 | disk-full problems on an NFS file system. | |
3379 | ||
3380 | - Restored the old daemon-server behavior of logging error messages rather | |
3381 | than returning them to the user. (A better long-term fix will be sought in | |
3382 | the future.) | |
3383 | ||
3384 | - An obscure uninitialized-variable bug was fixed in the uid/gid code. (This | |
3385 | bug probably had no ill effects.) | |
3386 | ||
3387 | ### BUILD CHANGES: | |
3388 | ||
3389 | - Got rid of the configure check for sys/sysctl.h (it wasn't used and was | |
3390 | causing a problem on some systems). Also improved the | |
3391 | broken-largefile-locking test to try to avoid failure due to an NFS | |
3392 | build-dir. | |
3393 | ||
3394 | - Fixed a compile problem on systems that don't define `AI_NUMERICHOST`. | |
3395 | ||
3396 | - Fixed a compile problem in the popt source for compilers that don't support | |
3397 | `__attribute__`. | |
3398 | ||
3399 | ### DEVELOPER RELATED: | |
3400 | ||
3401 | - Improved the testsuite's `merge` test to work on OSF1. | |
3402 | ||
3403 | - Two new diffs were added to the patches dir. | |
3404 | ||
3405 | ------------------------------------------------------------------------------ | |

3407 | ||
3408 | # NEWS for rsync 2.6.1 (26 Apr 2004) | |
3409 | ||
3410 | Protocol: 28 (changed) | |
3411 | ||
3412 | ## Changes since 2.6.0: | |
3413 | ||
3414 | ### SECURITY FIXES: | |
3415 | ||
3416 | - Paths sent to an rsync daemon are more thoroughly sanitized when chroot is | |
3417 | not used. If you're running a non-read-only rsync daemon with chroot | |
3418 | disabled, **please upgrade**, ESPECIALLY if the user privs you run rsync | |
3419 | under is anything above `nobody`. | |
3420 | ||
3421 | ### ENHANCEMENTS: | |
3422 | ||
3423 | - Lower memory use, more optimal transfer of data over the socket, and lower | |
3424 | CPU usage (see the INTERNAL section for details). | |
3425 | ||
3426 | - The `RSYNC_PROXY` environment variable can now contain a `USER:PASS@` prefix | |
3427 | before the `HOST:PORT` information. (Bardur Arantsson) | |
3428 | ||
3429 | - The `--progress` output now mentions how far along in the transfer we are, | |
3430 | including both a count of files transferred and a percentage of the total | |
3431 | file-count that we've processed. It also shows better | |
3432 | current-rate-of-transfer and remaining-transfer-time values. | |
3433 | ||
3434 | - Documentation changes now attempt to describe some often mis- understood | |
3435 | features more clearly. | |
3436 | ||
3437 | ### BUG FIXES: | |
3438 | ||
3439 | - When `-x` (`--one-file-system`) is combined with `-L` (`--copy-links`) or | |
3440 | `--copy-unsafe-links,` no symlinked files are skipped, even if the referent | |
3441 | file is on a different filesystem. | |
3442 | ||
3443 | - The `--link-dest` code now works properly for a non-root user when (1) the | |
3444 | UIDs of the source and destination differ and `-o` was specified, or (2) | |
3445 | when the group of the source can't be used on the destination and `-g` was | |
3446 | specified. | |
3447 | ||
3448 | - Fixed a bug in the handling of `-H` (hard-links) that might cause the | |
3449 | expanded PATH/NAME value of the current item to get overwritten (due to an | |
3450 | expanded-name caching bug). | |
3451 | ||
3452 | - We now reset the `new data has been sent` flag at the start of each file we | |
3453 | send. This makes sure that an interrupted transfer with the `--partial` | |
3454 | option set doesn't keep a shorter temp file than the current basis file when | |
3455 | no new data has been transferred over the wire for that file. | |
3456 | ||
3457 | - Fixed a byte-order problem in `--batch-mode` on big-endian machines. (Jay | |
3458 | Fenlason) | |
3459 | ||
3460 | - When using `--cvs-exclude`, the exclude items we get from a per-directory's | |
3461 | .cvsignore file once again only affect that one directory (not all following | |
3462 | directories too). The items are also now properly word-split and parsed | |
3463 | without any +/- prefix parsing. | |
3464 | ||
3465 | - When specifying the USER@HOST: prefix for a file, the USER part can now | |
3466 | contain an '@', if needed (i.e. the last '@' is used to find the HOST, not | |
3467 | the first). | |
3468 | ||
3469 | - Fixed some bugs in the handling of group IDs for non-root users: (1) It | |
3470 | properly handles a group that the sender didn't have a name for (it would | |
3471 | previously skip changing the group on any files in that group). (2) If | |
3472 | `--numeric-ids` is used, rsync no longer attempts to set groups that the | |
3473 | user doesn't have the permission to set. | |
3474 | ||
3475 | - Fixed the `refuse options` setting in the rsyncd.conf file. | |
3476 | ||
3477 | - Improved the `-x` (`--one-file-system`) flag's handling of any mount- point | |
3478 | directories we encounter. It is both more optimal (in that it no longer does | |
3479 | a useless scan of the contents of the mount- point dirs) and also fixes a | |
3480 | bug where a remapped mount of the original filesystem could get discovered | |
3481 | in a subdir we should be ignoring. | |
3482 | ||
3483 | - Rsync no longer discards a double-slash at the start of a filename when | |
3484 | trying to open the file. It also no longer constructs names that start with | |
3485 | a double slash (unless the user supplied them). | |
3486 | ||
3487 | - Path-specifying options to a daemon should now work the same with or without | |
3488 | chroot turned on. Previously, such a option (such as `--link-dest`) would | |
3489 | get its absolute path munged into a relative one if chroot was not on, | |
3490 | making that setting fairly useless. Rsync now transforms the path into one | |
3491 | that is based on the module's base dir when chroot is not enabled. | |
3492 | ||
3493 | - Fixed a compatibility problem interacting with older rsync versions that | |
3494 | might send us an empty `--suffix` value without telling us that | |
3495 | `--backup-dir` was specified. | |
3496 | ||
3497 | - The `hosts allow` option for a daemon-over-remote-shell process now has | |
3498 | improved support for IPv6 addresses and a fix for systems that have a length | |
3499 | field in their socket structs. | |
3500 | ||
3501 | - Fixed the ability to request an empty backup `--suffix` when sending files | |
3502 | to an rsync daemon. | |
3503 | ||
3504 | - Fixed an option-parsing bug when `--files-from` was sent to a server sender. | |
3505 | ||
3506 | ### INTERNAL: | |
3507 | ||
3508 | - Most of the I/O is now buffered, which results in a pretty large speedup | |
3509 | when running under MS Windows. (Craig Barratt) | |
3510 | ||
3511 | - Optimizations to the name-handling/comparing code have made some significant | |
3512 | reductions in user-CPU time for large file sets. | |
3513 | ||
3514 | - Some cleanup of the variable types make the code more consistent. | |
3515 | ||
3516 | - Reduced memory requirements of hard link preservation. (J.W. Schultz) | |
3517 | ||
3518 | - Implemented a new algorithm for hard-link handling that speeds up the code | |
3519 | significantly. (J.W. Schultz and Wayne Davison) | |
3520 | ||
3521 | - The `--hard-link` option now uses the first existing file in the group of | |
3522 | linked files as the basis for the transfer. This prevents the sub-optimal | |
3523 | transfer of a file's data when a new hardlink is added on the sending side | |
3524 | and it sorts alphabetically earlier in the list than the files that are | |
3525 | already present on the receiving side. | |
3526 | ||
3527 | - Dropped support for protocol versions less than 20 (2.3.0 released 15 Mar | |
3528 | 1999) and activated warnings for protocols less than 25 (2.5.0 released 23 | |
3529 | Aug 2001). (Wayne Davison and J.W. Schultz, severally) | |
3530 | ||
3531 | - More optimal data transmission for `--hard-links` (protocol 28). | |
3532 | ||
3533 | - More optimal data transmission for `--checksum` (protocol 28). | |
3534 | ||
3535 | - Less memory is used when `--checksum` is specified. | |
3536 | ||
3537 | - Less memory is used in the file list (a per-file savings). | |
3538 | ||
3539 | - The generator is now better about not modifying the file list during the | |
3540 | transfer in order to avoid a copy-on-write memory bifurcation (on systems | |
3541 | where fork() uses shared memory). Previously, rsync's shared memory would | |
3542 | slowly become unshared, resulting in real memory usage nearly doubling on | |
3543 | the receiving side by the end of the transfer. Now, as long as permissions | |
3544 | are being preserved, the shared memory should remain that way for the entire | |
3545 | transfer. | |
3546 | ||
3547 | - Changed hardlink info and `file_struct` + strings to use allocation pools. | |
3548 | This reduces memory use for large file-sets and permits freeing memory to | |
3549 | the OS. (J.W. Schultz) | |
3550 | ||
3551 | - The 2 pipes used between the receiver and generator processes (which are | |
3552 | forked on the same machine) were reduced to 1 pipe and the protocol improved | |
3553 | so that (1) it is now impossible to have the `redo` pipe fill up and hang | |
3554 | rsync, and (2) trailing messages from the receiver don't get lost on their | |
3555 | way through the generator over to the sender (which mainly affected | |
3556 | hard-link messages and verbose `--stats` output). | |
3557 | ||
3558 | - Improved the internal uid/gid code to be more portable and a little more | |
3559 | optimized. | |
3560 | ||
3561 | - The device numbers sent when using `--devices` are now sent as separate | |
3562 | major/minor values with 32-bit accuracy (protocol 28). Previously, the | |
3563 | copied devices were sent as a single 32-bit number. This will make | |
3564 | inter-operation of 64-bit binaries more compatible with their 32-bit | |
3565 | brethren (with both ends of the connection are using protocol 28). Note that | |
3566 | optimizations in the binary protocol for sending the device numbers often | |
3567 | results in fewer bytes being used than before, even though more precision is | |
3568 | now available. | |
3569 | ||
3570 | - Some cleanup of the exclude/include structures and its code made things | |
3571 | clearer (internally), simpler, and more efficient. | |
3572 | ||
3573 | - The reading & writing of the file-list in batch-mode is now handled by the | |
3574 | same code that sends & receives the list over the wire. This makes it much | |
3575 | easier to maintain. (Note that the batch code is still considered to be | |
3576 | experimental.) | |
3577 | ||
3578 | ### BUILD CHANGES: | |
3579 | ||
3580 | - The configure script now accepts `--with-rsyncd-conf=PATH` to override the | |
3581 | default value of the /etc/rsyncd.conf file. | |
3582 | ||
3583 | - Fixed configure bug when running `./configure --disable-ipv6`. | |
3584 | ||
3585 | - Fixed compilation problem on Tru64 Unix (having to do with `sockaddr.sa_len` | |
3586 | and `sockaddr.sin_len`). | |
3587 | ||
3588 | ### DEVELOPER RELATED: | |
3589 | ||
3590 | - Fixed `make test` bug when build dir is not the source dir. | |
3591 | ||
3592 | - Added a couple extra diffs in the `patches` dir, removed the ones that got | |
3593 | applied, and rebuilt the rest. | |

3598 | # NEWS for rsync 2.6.0 (1 Jan 2004) | |
3599 | ||
3600 | Protocol: 27 (changed) | |
3601 | ||
3602 | ## Changes since 2.5.7: | |
3603 | ||
3604 | ### ENHANCEMENTS: | |
3605 | ||
3606 | - `ssh` is now the default remote shell for rsync. If you want to change this, | |
3607 | configure like this: `./configure --with-rsh=rsh`. | |
3608 | ||
3609 | - Added `--files-from`, `--no-relative`, `--no-implied-dirs`, and `--from0`. | |
3610 | Note that `--from0` affects the line-ending character for all the files read | |
3611 | by the `--*-from` options. (Wayne Davison) | |
3612 | ||
3613 | - Length of csum2 is now per-file starting with protocol version | |
3614 | 27. (J.W. Schultz) | |
3615 | ||
3616 | - Per-file dynamic block size is now sqrt(file length). The per-file checksum | |
3617 | size is determined according to an algorithm provided by Donovan Baarda | |
3618 | which reduces the probability of rsync algorithm corrupting data and falling | |
3619 | back using the whole md4 checksums. (J.W. Schultz, Donovan Baarda) | |
3620 | ||
3621 | - The `--stats` option no longer includes the (debug) malloc summary unless | |
3622 | the verbose option was specified at least twice. | |
3623 | ||
3624 | - Added a new error/warning code for when files vanish from the sending side. | |
3625 | Made vanished source files not interfere with the file-deletion pass when | |
3626 | `--delete-after` was specified. | |
3627 | ||
3628 | - Various trailing-info sections are now preceded by a newline. | |
3629 | ||
3630 | ### BUG FIXES: | |
3631 | ||
3632 | - Fixed several exclude/include matching bugs when using wild-cards. This has | |
3633 | a several user-visible effects, all of which make the matching more | |
3634 | consistent and intuitive. This should hopefully not cause anyone problems | |
3635 | since it makes the matching work more like what people are expecting. (Wayne | |
3636 | Davison) | |
3637 | ||
3638 | - A pattern with a `**` no longer causes a `*` to match slashes. For example, | |
3639 | with `/*/foo/**`, `foo` must be 2 levels deep. [If your string has BOTH `*` | |
3640 | and `**` wildcards, changing the `*` wildcards to `**` will provide the old | |
3641 | behavior in all versions.] | |
3642 | ||
3643 | - `**/foo` now matches at the base of the transfer (like /foo does). [Use | |
3644 | `/**/foo` to get the old behavior in all versions.] | |
3645 | ||
3646 | - A non-anchored wildcard term floats to match beyond the base of the | |
3647 | transfer. E.g. `CVS/R*` matches at the end of the path, just like the | |
3648 | non-wildcard term `CVS/Root` does. [Use `/CVS/R*` to get the old behavior in | |
3649 | all versions.] | |
3650 | ||
3651 | - Including a `**` in the match term causes it to be matched against the | |
3652 | entire path, not just the name portion, even if there aren't any interior | |
3653 | slashes in the term. E.g. `foo**bar` would exclude `/path/foo-bar` (just | |
3654 | like before) as well as `/foo-path/baz-bar` (unlike before). [Use `foo*bar` | |
3655 | to get the old behavior in all versions.] | |
3656 | ||
3657 | - The exclude list specified in the daemon's config file is now properly | |
3658 | applied to the pulled items no matter how deep the user's file-args are in | |
3659 | the source tree. (Wayne Davison) | |
3660 | ||
3661 | - For protocol version >= 27, `mdfour_tail()` is called when the block size | |
3662 | (including `checksum_seed`) is a multiple of 64. Previously it was not | |
3663 | called, giving the wrong MD4 checksum. (Craig Barratt) | |
3664 | ||
3665 | - For protocol version >= 27, a 64 bit bit counter is used in mdfour.c as | |
3666 | required by the RFC. Previously only a 32 bit bit counter was used, causing | |
3667 | incorrect MD4 file checksums for file sizes >= 512MB - 4. (Craig Barratt) | |
3668 | ||
3669 | - Fixed a crash bug when interacting with older rsync versions and multiple | |
3670 | files of the same name are destined for the same dir. (Wayne Davison) | |
3671 | ||
3672 | - Keep tmp names from overflowing MAXPATHLEN. | |
3673 | ||
3674 | - Make `--link-dest` honor the absence of `-p`, `-o`, and `-g`. | |
3675 | ||
3676 | - Made rsync treat a trailing slash in the destination in a more consistent | |
3677 | manner. | |
3678 | ||
3679 | - Fixed file I/O error detection. (John Van Essen) | |
3680 | ||
3681 | - Fixed bogus `malformed address {hostname}` message in rsyncd log when | |
3682 | checking IP address against hostnames from `hosts allow` and `hosts deny` | |
3683 | parameters in config file. | |
3684 | ||
3685 | - Print heap statistics when verbose >= 2 instead of when >= 1. | |
3686 | ||
3687 | - Fixed a compression (`-z`) bug when syncing a mostly-matching file that | |
3688 | contains already-compressed data. (Yasuoka Masahiko and Wayne Davison) | |
3689 | ||
3690 | - Fixed a bug in the `--backup` code that could cause deleted files to not get | |
3691 | backed up. | |
3692 | ||
3693 | - When the backup code makes new directories, create them with mode 0700 | |
3694 | instead of 0755 (since the directory permissions in the backup tree are not | |
3695 | yet copied from the main tree). | |
3696 | ||
3697 | - Call setgroups() in a more portable manner. | |
3698 | ||
3699 | - Improved file-related error messages to better indicate exactly what | |
3700 | pathname failed. (Wayne Davison) | |
3701 | ||
3702 | - Fixed some bugs in the handling of `--delete` and `--exclude` when using the | |
3703 | `--relative` (`-R`) option. (Wayne Davison) | |
3704 | ||
3705 | - Fixed bug that prevented regular files from replacing special files and | |
3706 | caused a directory in `--link-dest` or `--compare-dest` to block the | |
3707 | creation of a file with the same path. A directory still cannot be replaced | |
3708 | by a regular file unless `--delete` specified. (J.W. Schultz) | |
3709 | ||
3710 | - Detect and report when open or opendir succeed but read and readdir fail | |
3711 | caused by network filesystem issues and truncated files. (David Norwood, | |
3712 | Michael Brown, J.W. Schultz) | |
3713 | ||
3714 | - Added a fix that should give ssh time to restore the tty settings if the | |
3715 | user presses Ctrl-C at an ssh password prompt. | |
3716 | ||
3717 | ### INTERNAL: | |
3718 | ||
3719 | - Eliminated vestigial support for old versions that we stopped supporting. | |
3720 | (J.W. Schultz) | |
3721 | ||
3722 | - Simplified some of the option-parsing code. (Wayne Davison) | |
3723 | ||
3724 | - Some cleanup made to the exclude code, as well as some new defines added to | |
3725 | enhance readability. (Wayne Davison) | |
3726 | ||
3727 | - Changed the protocol-version code so that it can interact at a lower | |
3728 | protocol level than the maximum supported by both sides. Added an | |
3729 | undocumented option, `--protocol=N`, to force the value we advertise to the | |
3730 | other side (primarily for testing purposes). (Wayne Davison) | |

3750 | ||
3751 | Protocol: 26 (unchanged) | |
3752 | ||
3753 | ## Changes since 2.5.5: | |
3754 | ||
3755 | ### ENHANCEMENTS: | |
3756 | ||
3757 | - The `--delete-after` option now implies `--delete`. (Wayne Davison) | |
3758 | ||
3759 | - The `--suffix` option can now be used with `--backup-dir`. (Michael | |
3760 | Zimmerman) | |
3761 | ||
3762 | - Combining `::` syntax with the `--rsh`/`-e` option now uses the specified | |
3763 | remote-shell as a transport to talk to a (newly-spawned) server-daemon. This | |
3764 | allows someone to use daemon features, such as modules, over a secure | |
3765 | protocol, such as ssh. (JD Paul) | |
3766 | ||
3767 | - The rsync:// syntax for daemon connections is now accepted in the | |
3768 | destination field. | |
3769 | ||
3770 | - If the file name given to `--include-from` or `--exclude-from` is `-`, rsync | |
3771 | will read from standard input. (J.W. Schultz) | |
3772 | ||
3773 | - New option `--link-dest` which is like `--compare-dest` except that | |
3774 | unchanged files are hard-linked in to the destination directory. (J.W. | |
3775 | Schultz) | |
3776 | ||
3777 | - Don't report an error if an excluded file disappears during an rsync run. | |
3778 | (Eugene Chupriyanov and Bo Kersey) | |
3779 | ||
3780 | - Added .svn to `--cvs-exclude` list to support subversion. (Jon Middleton) | |
3781 | ||
3782 | - Properly support IPv6 addresses in the rsyncd.conf `hosts allow` and `hosts | |
3783 | deny` fields. (Hideaki Yoshifuji) | |
3784 | ||
3785 | - Changed exclude file handling to permit DOS or MAC style line terminations. | |
3786 | (J.W. Schultz) | |
3787 | ||
3788 | - Ignore errors from chmod when `-p`/`-a`/`--preserve-perms` is not set. | |
3789 | (Dave Dykstra) | |
3790 | ||
3791 | ### BUG FIXES: | |
3792 | ||
3793 | - Fix `forward name lookup failed` errors on AIX 4.3.3. (John L. Allen, Martin | |
3794 | Pool) | |
3795 | ||
3796 | - Generate each file's rolling-checksum data as we send it, not in a separate | |
3797 | (memory-eating) pass before hand. This prevents timeout errors on really | |
3798 | large files. (Stefan Nehlsen) | |
3799 | ||
3800 | - Fix compilation on Tru64. (Albert Chin, Zoong Pham) | |
3801 | ||
3802 | - Better handling of some client-server errors. (Martin Pool) | |
3803 | ||
3804 | - Fixed a crash that would occur when sending a list of files that contains a | |
3805 | duplicate name (if it sorts to the end of the file list) and using | |
3806 | `--delete`. (Wayne Davison) | |
3807 | ||
3808 | - Fixed the file-name duplicate-removal code when dealing with multiple dups | |
3809 | in a row. (Wayne Davison) | |
3810 | ||
3811 | - Fixed a bug that caused rsync to lose the exit status of its child processes | |
3812 | and sometimes return an exit code of 0 instead of showing an error. (David | |
3813 | R. Staples, Dave Dykstra) | |
3814 | ||
3815 | - Fixed bug in `--copy-unsafe-links` that caused it to be completely broken. | |
3816 | (Dave Dykstra) | |
3817 | ||
3818 | - Prevent infinite recursion in cleanup code under certain circumstances. | |
3819 | (Sviatoslav Sviridov and Marc Espie) | |
3820 | ||
3821 | - Fixed a bug that prevented rsync from creating intervening directories when | |
3822 | `--relative-paths`/`-R` is set. (Craig Barratt) | |
3823 | ||
3824 | - Prevent `Connection reset by peer` messages from Cygwin. (Randy O'Meara) | |
3825 | ||
3826 | ### INTERNAL: | |
3827 | ||
3828 | - Many code cleanups and improved internal documentation. (Martin Pool, Nelson | |
3829 | Beebe) | |
3830 | ||
3831 | - Portability fixes. (Dave Dykstra and Wayne Davison) | |
3832 | ||
3833 | - More test cases. (Martin Pool) | |
3834 | ||
3835 | - Some test-case fixes. (Brian Poole, Wayne Davison) | |
3836 | ||
3837 | - Updated included popt to the latest vendor drop, version 1.6.4. (Jos | |
3838 | Backus) | |
3839 | ||
3840 | - Updated config.guess and config.sub to latest versions; this means rsync | |
3841 | should build on more platforms. (Paul Green) | |

3847 | ||
3848 | Protocol: 26 (unchanged) | |
3849 | ||
3850 | ## Changes since 2.5.4: | |
3851 | ||
3852 | ### ENHANCEMENTS: | |
3853 | ||
3854 | - With `--progress`, when a transfer is complete show the time taken; | |
3855 | otherwise show expected time to complete. (Cameron Simpson) | |
3856 | ||
3857 | - Make `make install-strip` works properly, and `make install` accepts a | |
3858 | DESTDIR variable for help in building binary packages. (Peter | |
3859 | Breitenlohner, Greg Louis) | |
3860 | ||
3861 | - If configured with `--enable-maintainer-mode`, then on receipt of a fatal | |
3862 | signal rsync will try to open an xterm running gdb, similarly to Samba's | |
3863 | `panic action` or GNOME's bug-buddy. (Martin Pool) | |
3864 | ||
3865 | ### BUG FIXES: | |
3866 | ||
3867 | - Fix situation where failure to fork (e.g. because out of process slots) | |
3868 | would cause rsync to kill all processes owned by the current user. Yes, | |
3869 | really! (Paul Haas, Martin Pool) | |
3870 | ||
3871 | - Fix test suite on Solaris. (Jos Backus, Martin Pool) | |
3872 | ||
3873 | - Fix minor memory leak in socket code. (Dave Dykstra, Martin Pool.) | |
3874 | ||
3875 | - Fix `--whole-file` problem that caused it to be the default even for remote | |
3876 | connections. (Martin Pool, Frank Schulz) | |
3877 | ||
3878 | - Work around bug in Mac OS X mkdir(2), which cannot handle trailing slashes. | |
3879 | <http://www.opensource.apple.com/bugs/X/BSD%20Kernel/2734739.html> (Martin | |
3880 | Pool) | |
3881 | ||

3894 | ||
3895 | - Additional fix for zlib double-free bug. (Martin Pool, Andrew Tridgell) (CVE | |
3896 | CAN-2002-0059) | |
3897 | ||
3898 | ### ENHANCEMENTS: | |
3899 | ||
3900 | - Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus) (Note that | |
3901 | rsync still uses a custom version of zlib; you can not just link against a | |
3902 | system library. See zlib/README.rsync) | |
3903 | ||

3912 | ||
3913 | ## Changes since 2.5.2: | |
3914 | ||
3915 | ### SECURITY FIXES: | |
3916 | ||
3917 | - Make sure that supplementary groups are removed from a server | |
3918 | process after changing uid and gid. (Ethan Benson) (Debian bug | |
3919 | #132272, CVE CAN-2002-0080) | |
3920 | ||
3921 | ### BUG FIXES: | |
3922 | ||
3923 | - Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE CAN-2002-0059) | |
3924 | ||
3925 | - Fixed problem that in many cases caused the error message unexpected read | |
3926 | size of 0 in `map_ptr` and resulted in the wrong data being copied. | |
3927 | ||
3928 | - Fixed compilation errors on some systems caused by the use of `unsigned | |
3929 | int64` in rsync.h. | |
3930 | ||
3931 | - Fixed problem on systems such as Sunos4 that do not support realloc on a | |
3932 | NULL pointer; error was 'out of memory in "flist_expand"'. | |
3933 | ||
3934 | - Fix for rsync server processes hanging around after the client unexpectedly | |
3935 | disconnects. (Colin Walters) (Debian bug #128632) | |
3936 | ||
3937 | - Cope with BSD systems on which mkdir() will not accept a trailing slash. | |
3938 | ||
3939 | ### ENHANCEMENTS: | |
3940 | ||
3941 | - Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that rsync still uses | |
3942 | a custom version of zlib; you can not just link against a system library. | |
3943 | See zlib/README.rsync) | |
3944 | ||
3945 | - Command to initiate connections is only shown with `-vv`, rather than `-v` | |
3946 | as in 2.5.2. Output from plain `-v` is more similar to what was historically | |
3947 | used so as not to break scripts that try to parse the output. | |
3948 | ||
3949 | - Added `--no-whole-file` and `--no-blocking-io` options (Dave Dykstra) | |
3950 | ||
3951 | - Made the `--write-batch` and `--read-batch` options actually work and added | |
3952 | documentation in the man page (Jos Backus) | |
3953 | ||
3954 | - If the daemon is unable to fork a child to accept a connection, print an | |
3955 | error message. (Colin Walters) | |

3961 | ||
3962 | Protocol: 26 (changed) | |
3963 | ||
3964 | ## Changes since 2.5.1: | |
3965 | ||
3966 | ### SECURITY FIXES: | |
3967 | ||
3968 | - Signedness security patch from Sebastian Krahmer <krahmer@suse.de> -- in | |
3969 | some cases we were not sufficiently careful about reading integers from the | |
3970 | network. | |
3971 | ||
3972 | ### BUG FIXES: | |
3973 | ||
3974 | - Fix possible string mangling in log files. | |
3975 | ||
3976 | - Fix for setting local address of outgoing sockets. | |
3977 | ||
3978 | - Better handling of hardlinks and devices on platforms with 64-bit `dev_t` or | |
3979 | `ino_t`. | |
3980 | ||
3981 | - Name resolution on machines supporting IPv6 is improved. | |
3982 | ||
3983 | - Fix for device nodes. (dann frazier) (Debian #129135) | |
3984 | ||
3985 | ### ENHANCEMENTS: | |
3986 | ||
3987 | - With `-v`, rsync now shows the command used to initiate an ssh/rsh | |
3988 | connection. | |
3989 | ||
3990 | - `--statistics` now shows memory heap usage on platforms that support | |
3991 | mallinfo(). | |
3992 | ||
3993 | - "The Ted T'so school of program optimization": make progress visible and | |
3994 | people will think it's faster. (With `--progress`, rsync will show you how | |
3995 | many files it has seen as it builds the `file_list`, giving some indication | |
3996 | that it has not hung.) | |
3997 | ||
3998 | - Improvements to batch mode support. This is still experimental but testing | |
3999 | would be welcome. (Jos Backus) | |
4000 | ||
4001 | - New `--ignore-existing` option, patch previously distributed with Vipul's | |
4002 | Razor. (Debian #124286) | |

4010 | ||
4011 | ## Changes since 2.5.0: | |
4012 | ||
4013 | ### BUG FIXES: | |
4014 | ||
4015 | - Fix for segfault in `--daemon` mode configuration parser. (Paul Mackerras) | |
4016 | ||
4017 | - Correct `string<->address` parsing for both IPv4 and 6. (YOSHIFUJI Hideaki, | |
4018 | SUMIKAWA Munechika and Jun-ichiro `itojun` Hagino) | |
4019 | ||
4020 | - Various fixes for IPv6 support. (Dave Dykstra) | |
4021 | ||
4022 | - rsync.1 typo fix. (Matt Kraai) | |
4023 | ||
4024 | - Test suite typo fixes. (Tom Schmidt) | |
4025 | ||
4026 | - rsync.1 grammar and clarity improvements. (Edward Welbourne) | |
4027 | ||
4028 | - Correction to ./configure tests for `inet_ntop`. (Jeff Garzik) | |
4029 | ||
4030 | ### ENHANCEMENTS: | |
4031 | ||
4032 | - `--progress` and `-P` now show estimated data transfer rate (in a multiple | |
4033 | of bytes/s) and estimated time to completion. (Rik Faith) | |
4034 | ||
4035 | - `--no-detach` option, required to run as a W32 service and also useful when | |
4036 | running on Unix under daemontools, AIX's SRC, or a debugger. (Max Bowsher, | |
4037 | Jos Backus) | |
4038 | ||
4039 | - Clearer error messages for some conditions. | |

4045 | ||
4046 | Protocol: 25 (changed) | |
4047 | ||
4048 | ## Changes since 2.4.6: | |
4049 | ||
4050 | ### ANNOUNCEMENTS: | |
4051 | ||
4052 | - Martin Pool <mbp@samba.org> is now a co-maintainer. | |
4053 | ||
4054 | ### NEW FEATURES: | |
4055 | ||
4056 | - Support for LSB-compliant packaging <http://www.linuxbase.org/> | |
4057 | ||
4058 | - Shell wildcards are allowed in `auth users` lines. | |
4059 | ||
4060 | - Merged UNC rsync+ patch to support creation of standalone patch sets. By | |
4061 | Bert J. Dempsey and Debra Weiss, updated by Jos Backus. | |
4062 | <http://www.ils.unc.edu/i2dsi/unc_rsync+.html> | |
4063 | ||
4064 | - IPv6 support based on a patch from KAME.net, on systems including modern | |
4065 | versions of Linux, Solaris, and HP-UX. Also includes IPv6 compatibility | |
4066 | functions for old OSs by the Internet Software Consortium, Paul Vixie, the | |
4067 | OpenSSH portability project, and OpenBSD. | |
4068 | ||
4069 | ### ENHANCEMENTS: | |
4070 | ||
4071 | - Include/exclude cluestick: with `-vv`, print out whether files are included | |
4072 | or excluded and why. | |
4073 | ||
4074 | - Many error messages have more friendly explanations and more details. | |
4075 | ||
4076 | - Manual page improvements plus scanty protocol documentation. | |
4077 | ||
4078 | - When running as `--daemon` in the background and using a `log file` | |
4079 | rsyncd.conf directive, close the log file every time it is open when going | |
4080 | to sleep on the socket. This allows the log file to get cleaned out by | |
4081 | another process. | |
4082 | ||
4083 | - Change to using libpopt rather than getopt for processing options. This | |
4084 | makes the code cleaner and the behaviour more consistent across platforms. | |
4085 | popt is included and built if not installed on the platform. | |
4086 | ||
4087 | - More details in `--version`, including note about whether 64-bit files, | |
4088 | symlinks and hardlinks are supported. | |
4089 | ||
4090 | - MD4 code may use less CPU cycles. | |
4091 | ||
4092 | - Use mkstemp on systems where it is secure. If we use mktemp, explain that we | |
4093 | do it in a secure way. | |
4094 | ||
4095 | - `--whole-file` is the default when source and target are on the local | |
4096 | machine. | |
4097 | ||
4098 | ### BUG FIXES: | |
4099 | ||
4100 | - Fix for various bugs causing rsync to hang. | |
4101 | ||
4102 | - Attempt to fix Large File Summit support on AIX. | |
4103 | ||
4104 | - Attempt to fix error handling lockup bug. | |
4105 | ||
4106 | - Give a non-0 exit code if **any** of the files we have been asked to | |
4107 | transfer fail to transfer. | |
4108 | ||
4109 | - For log messages containing ridiculously long strings that might overflow a | |
4110 | buffer rsync no longer aborts, but rather prints an ellipsis at the end of | |
4111 | the string. (Patch from Ed Santiago.) | |
4112 | ||
4113 | ### PLATFORMS: | |
4114 | ||
4115 | - Improved support for UNICOS (tested on Cray T3E and Cray SV1) | |
4116 | ||
4117 | - autoconf2.52 (or later) is now required to rebuild the autoconf scripts. It | |
4118 | is not required to simply build rsync. | |
